< 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. Summary of Features : - LS26VNS (N-Channel Single) - RDS(on) 14-38 Ω - BVgss 30 Volts - Available in TO-92 3L, SOT-23 3L, DFN 8L, and Bare Die options - LS26VPS (P-Channel Single) - RDS(on) 20-50 Ω - BVgss 30 Volts - Available in TO-92 3L, SOT-23 3L, DFN 8L, and Bare Die options Applications: - Variable Gain Controls - Voltage Controlled Oscillators - Signal Attenuators - Musical Effects Applications - Adaptive Analog Filters - Automatic Gain Control Circuits - Clock Generators - Compressors - Electrometers - Energy Harvesters - Expanders - Hearing Aids - Light Dimmers - Modulators - Mixers - Artificial Neural Networks - Programmable Gain Amplifiers - Phased Arrays - Phase Lock Loops - Phase Controlled Dimming Circuits - Phase Delay and Advance Circuits - Tunable Filters - Variable Attenuators - Voltage Controlled Multivibrators - Waveform Generators Pricing and Availability: - 1,000+ pieces of the LS26VNS and LS26VPS in the TO-92 3L, SOT-23 3L, and DFN 8L packages are priced at $1.23 (USD) each. - Production quantities are available now with delivery from factory stock to 8 weeks.

< Back FAST SAMPLE AND HOLD Linear Systems Jun 10, 2024 In this interesting design, a strobe pulse sets the sample mode. Here's how it works: When the strobe pulse s —Strobe pulse will turn on JFET Q1 which allows the signal to be sampled to charge capacitor C1. When the strobe pulse returns to 0 V, JFET Q1 is turned off and capacitor C1 holds the voltage value of the sampled signal plus the offset voltage of MOSFET Q 2. The JFET used could be anyone of Linear Integrated Systems switch JFETs. Ideally the lower the drain -to-source voltage the better to reduce the offset voltage of the JFET. The output signal decays at a rate of 1 mV/s. From logic input of 531 op-amp IC2 turns on JFET Q1 to complete feedback loop to IC1, Q1, and Q2. Capacitor C1 charges to voltage equal to that of input signal plus gate-to-source offset voltage of Q2. At end of strobe time, feedback loop is broken and C1 holds voltage until time of next strobe pulse. Decay in output voltage between samplings is 1 mV/s.—"Signetics Analog Data Manual," Signetics, Sunnyvale, CA, 1977, p 643-644.
