< Back LS844 App Note Introduction Introduction For circuits designed to work with high impedance sources, ranging from electrometers to microphone preamplifiers, the use of a low-noise, high-impedance device between the input and the op amp is needed in order to optimize performance. At first glance, one of Linear Systems’ most popular parts, the LSK389 ultra-low-noise dual JFET would appear to be a good choice for such an application. The part’s high input impedance (1 T) and low noise (1 nV/√Hz at 1kHz and 2mA drain current) enables power transfer while adding almost no noise to the signal. But further examination of the LSK389’s specification shows an input capacitance of over 20pF. This will cause intermodulation distortion as the circuit’s input signal increases in frequency if the source impedance is high. This is because the JFET junction capacitances are nonlinear. This will be especially the case where common source amplifier arrangements allow the Miller effect to multiply the effective value of the gatedrain capacitance. Further, the LSK389’s input impedance will fall to a lower value as the frequency increases relative to a part with lower input capacitance. A better design choice is Linear Systems’ LS844. Though the LS844 has slightly higher noise (2.5 nV/√Hz vs. 1.0 nV/√Hz) its much lower input capacitance of only 4pF means that it will maintain its high input impedance as the frequency of the input signal rises. More importantly, using the lower-capacitance LS844 will create a circuit that is much less susceptible to intermodulation distortion than one using the LSK389. The LS844’s lower gate-to-drain capacitance enables more effective, elegant audio circuit designs. The relatively high capacitance of the LSK389 often requires designers to use a cascode circuit to provide the ability to handle higher bandwidths without intermodulation distortion. The cascode does this by eliminating the Miller effect that can multiply the effective gate-drain capacitance and its associated nonlinear effects. However, the cascode adds complexity and noise contributed by the cascode transistors. The LS844 is an N-channel dual low-noise, lowcapacitance, tightly matched monolithic field effect transistor. It features: • 3ms transconductance at 2mA drain current • 1000 G input impedance • 60V breakdown voltage • gate-drain capacitance of only 1.5pF • 4pF input capacitance • 2.5 nV/√Hz noise at 1kHz • best low-noise/low-capacitance combination in the industry • lowest input capacitance per unit gate length in the industry • lowest noise for a given gate length in the industry • tight Vgs matching at operating bias The LS844 is particularly well suited to low-noise, highgain audio and instrumentation circuits operating from battery voltages up to 60 volts. 48V phantom-powered circuits, like those used in microphone preamplifiers, are especially benefited by the features of the LS844. Low operating Vgs, high gm, tight matching, low noise and low capacitance make it well-suited to numerous audio and instrumentation applications. Sensors, which play such an important role in today’s world, benefit greatly from the performance delivered by the LS844. Such sensor technologies include piezo, quartz, condenser, electret, and MEMs devices. These devices benefit from the LS844’s combination of low input capacitance and low noise. Electrometer applications also benefit from these characteristics. Read More

< Back Solving the Noise Puzzle Introduction Noise is one of the more important aspects of circuit design. Lower noise in audio amplifier design means better quality audio. Low-noise in instrument design means more reliable and accurate measurements at lower voltage and current levels. And low-noise in current source designs means less noise injected into the electronic system. One of the most basic approaches to reduce noise in an amplifier is to use low-noise components. This would include low-noise bipolar transistors and low-valued resistors. Although one can use low-noise operational amplifiers in the design of low-noise circuits or low-noise current sources it is often not done. This is because lower noise can be often be obtained with a well-thought out discrete design. And that’s because discrete transistors offer much more design customization capability for specific circuit applications – like optimized collector biasing. One must remember that monolithic chip designs are built for the most part for general purpose applications. It is hard to tailor a specific op amp or current source chip for a specific source resistance, specific power consumption requirement and a specific bandwidth that will lower the overall noise – that is unless you add-on more compensation components.

< Back LSJ689 Press Release Linear Systems Mar 17, 2023 Ultra Low Noise P-Channel Dual JFET NEWS RELEASE CONTACT: Linear Integrated Systems, Inc. 510-490-9160 sales@linearsystems.com LINEAR INTEGRATED SYSTEMS ANNOUNCES ULTRA LOW NOISE P-CHANNEL DUAL JFET Fremont, California – June 1, 2016 – Linear Integrated Systems, a leading full-service manufacturer of specialty linear semiconductors, announces the immediate availability of its LSJ689, a 1.8 nV/Hz @ 1kHz, low-capacitance, monolithic dual P-Channel JFET. The LSJ689 serves as the P-Channel complement to the popular monolithic dual N-Channel JFET, the LSK489. This addition to Linear Systems' family of Ultra-Low-Noise JFETs provides designers with expanded options beyond traditional N-Channel JFETs. The monolithic dual construction of the LSJ689 and LSK489 offers superior solutions for tighter Idss (drain-source saturation current) matching and improved thermal tracking compared to using individually matched JFETs. As the availability of P-Channel JFETs has declined, complementary single N-Channel and P-Channel JFETs have become increasingly limited to a few industry standards. In response, Linear Systems developed the LSK170 and LSJ74 families, providing complementary N & P-Channel single JFETs. Now, the LSJ689 and LSK489 monolithic dual JFETs provide further design flexibility, with significantly lower capacitance—4 pF versus the 25 pF of LSK170 and LSJ74. The LSJ689 and LSK489 are well-suited for differential input stages in amplifier, phono, and preamplifier designs. Additional applications include voltage-controlled resistors, thermal stable source followers, sample and hold circuits, and current matched sources.

< Back LS26VPS/VNS Press Release Linear Systems Mar 17, 2023 New JFET Voltage-Controlled Resistors NEWS RELEASE FOR INFORMATION CONTACT: Linear Systems, Inc. Sales Department Phone: (510) 490-9160 Email: sales@linearsystems.com Build lower-voltage, lower-power circuits using Linear Systems' industry-leading voltage-controlled resistors. Linear Systems has expanded its family of JFET Voltage-Controlled Resistors (VCRs) for reduced-power circuits over IC-based devices. Two new additions to the JFET Voltage-Controlled Resistor Family include the LS26VNS, a Single N-Channel JFET VCR, and the LS26VPS, a Single P-Channel JFET VCR. Both the N and P-channel versions are made from the same die geometry, making them complementary. They join the existing VCR11N, a Dual N-Channel VCR. The advantages of using VCRs for voltage-controlled amplifier or voltage-controlled gain systems include: - VCR-based devices operate with lower voltage and power consumption, enabling battery-powered systems to last significantly longer. - VCR JFETs can be used with low-power op amps to provide a low-power solution for voltage-controlled gain systems. - With low voltage op amps such as the LMV358 or TLC272, VCR JFETs perform voltage-controlled gain at extremely low supply voltages, down to a single 3.3V power supply. Circuits can be designed for very low power consumption when combined with low voltage, low power op amps. For instance, using an LSK389A as a VCR for these low voltage circuits can provide significant efficiency gains. - Matched pair JFET VCRs (VCR11N or LSK389A) can provide two identical channels of voltage-controlled gain, where the control voltage tracks both channels. This can be used in stereo audio signal attenuation. In contrast, typical active voltage-controlled amplifiers drain more current and require higher minimum power supply voltages, needing at least +/- 4 volts for a specialized voltage control amplifier integrated circuit. P-Channel JFETs, including a J177, can be designed as a VCR circuit with a single power supply. For example, the P-Channel JFET VCR circuit is ideal with positive supply voltages since its control voltage to the gate is also positive. Product Details: - LS26VNS N-Channel Single JFET VCR: Drain-source resistance is controlled by a DC bias voltage (VGS) applied to a high impedance gate terminal. Minimum RDS of 14 Ω occurs when VGS = -1.0V. As VGS approaches the pinch-off voltage of -6.0V, RDS rapidly increases to the maximum value of 38 Ω. - LS26VPS P-Channel Single JFET VCR: Drain-source resistance is controlled by a DC bias voltage (VGS) applied to a high impedance gate terminal. Minimum RDS of 20 Ω occurs when VGS = 3.0V. As VGS approaches the pinch-off voltage of 7.5V, RDS rapidly increases to the maximum value of 50 Ω.
