P-CHANNEL JFET, VOLTAGE CONTROLLED RESISTOR < Back LS26VPS_ P-CHANNEL JFET, VOLTAGE CONTROLLED RESISTOR The LS26VPS is a P-Channel Single JFET voltage-controlled resistor. It has a drain-source resistance that 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 or RDS = 50 Ω. For the N-Channel version, please see our LS26VNS. Both the N and P-channel parts are made from the same die geometry, making them complimentary.

< 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. These parts also provide the front-end amplification for high-end test and measurement, medical and audio equipment. Linear Systems is a full-service, privately-held, designer and manufacturer of small-signal discrete semiconductors established in 1987. The Fremont, CA-based company was founded by John H. Hall, co-founder of Intersil and founder of Micro Power Systems. Linear Systems' product line consists of: Ultra-Low-Noise N-Channel and P-Channel Dual and Single JFETs, High-Speed Lateral DMOS Switches, Bipolar Transistors, BIFET Amplifiers, Current-Regulating Diodes, Low-Leakage Diodes, MOSFETs, PhotoFETS, and Voltage Controlled Resistors.
