January 25, 2005 Linear Integrated Systems, a leading full-service manufacturer of specialty linear semiconductors, announces the immediate availability of its LSK170 series of JFETs, optimized to provide low noise at both high and low frequency with a narrow range of IDSS and low capacitance. The LSK170's low noise to capacitance ratio and narrow range of low value IDSS provide solutions for low noise applications which cannot tolerate high values of capacitance or wide ranges of IDSS. The LSK170 offers a voltage noise (en) of 1nv/hz @ 1khz, 2nv/hz @ 10hz typical and a High Gain (yfs, 22ms), with only 22pf of capacitance (Ciss). This series has three grades of IDSS range: 2.6-6mA, 6.0-12mA, and 10-20mA. The narrow ranges of IDSS binning with the LSK170 promote ease of design tolerancing, particularly in low voltage applications. The LSK170 is ideal for portable battery operated applications, and features high BVDSS for maximum linear headroom in high transient program content amplifiers. The series has a uniquely linear VGS transfer function for a stability that is highly desirable, particularly for audio front-end preamplifiers. The device is available in surface mount SOT-23 and thru-hole TO-92 packages. The surface mount version of the LSK170 series creates new opportunities for engineers seeking to design lower noise circuits in compact embeddable applications where shielding and space is critical and are not supported with the traditional TO-92 package. The LSK170 series is a pin for pin replacement of the Toshiba 2SK170 and improved functional replacement for the Interfet IF1320, IF1330, IF1331, and IF4500.

< Back Testing Capability Linear Systems Mar 17, 2023 New Low-Noise Semiconductor Testing Capability FREMONT, Calif., April 11, 2019 /PRNewswire/ -- Linear Integrated Systems, Inc. (Linear Systems) will be unveiling its large-scale sub-nanovolt parts testing capability at the 23rd Annual Conference and Exhibition for Components for Military & Space Electronics (CMSE) in Los Angeles. This testing capability enables individual screening of small-signal discrete components to levels below a billionth of a volt (nV/√Hz) of noise in quantities up to tens of thousands of parts. Linear Systems created this capability in response to a U.S. defense program requirement and is now providing ultra-low-noise-screened parts to other customers. "Small-signal discrete components can help create the lowest noise signal chains possible and that's what our customers have been demanding," said Timothy S. McCune. "This sub-nanovolt testing capability enables us to provide production-line quantities of parts guaranteed to meet specific noise levels. No other company has this capability." Linear Systems will be available to discuss this capability and its line of precision small-signal discrete components at the 23rd Annual Conference and Exhibition for Components for Military & Space Electronics (CMSE) to be held at the Four Points by Sheraton (LAX), Los Angeles on April 16-18. CMSE is the premier event focused on the design, reliability, and application of electronic components for use in avionics aerospace, military & commercial space systems. The conference provides access to more than 30 technical presentations by industry leaders, focused on advanced packaging of ICs, passive components, and a number of other topics critical to components used in high reliability military and aerospace systems. Linear Systems specializes in the development and manufacture of precision, ultra-low-noise small-signal discrete components. Its parts, such as the LSK389 and LSK489, are used in highly demanding sensor systems ranging from the Large-Scale Synoptic Telescope to piezoelectric devices to sonobuoys.

< Back LSK489 App Note 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 TΩ) 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 gate-drain 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’ new offering, the LSK489. Though the LSK489 has slightly higher noise (1.5 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 LSK489 will create a circuit that is much less susceptible to intermodulation distortion than one using the LSK389. The LSK489’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 LSK489 is an N-channel dual low-noise, low-capacitance, tightly matched monolithic field effect transistor. It features: • 3ms transconductance at 2mA drain current • 1000 GΩ input impedance • 60V breakdown voltage • gate-drain capacitance of only 1.5pF • 4pF input capacitance • 1.5 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 Read More
