< 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. The LSJ689 is available in RoHS-compliant SOT-23 6L, SOIC-A 8L, and TO-71 6L package options. The SOT-23 6L and SOIC-A 8L packages are ideal for space-constrained circuits in audio and instrumentation applications. Key Features: - Complement to the Ultra Low Noise Monolithic Dual N-Channel JFET LSK489 - Ultra Low Noise (typically 1.8 nV/Hz @ 1kHz) - Nearly Zero Popcorn Noise - Idss (drain-source saturation current) matching to 10% max - Low Offset/Tight Matching (|Vgs1 - Vgs2| = 20mV max) - Low Capacitance (Ciss = 4 pF) - High Input Impedance - High Breakdown Voltage (BVGSS = 40V Min) - Monolithic Dual (2 JFETs on one piece of silicon, offering better matching and thermal tracking) - Available in Surface Mount SOIC-A 8L and compact SOT-23 6L packages - Lead-free/RoHS Compliant Applications: - Microphone Amplifiers, Phono Preamplifiers, Audio Amplifiers, and Preamps - Discrete Low-Noise Operational Amplifiers - Battery-Operated Audio Preamps - Audio Mixer Consoles, Acoustic Sensors, Sonic Imaging - Instrumentation Amplifiers - Wideband Differential Amplifiers - High-Speed Comparators - Impedance Converters - Voltage-Controlled Resistors, Sample and Hold, Source Followers Availability: Sampling now in SOIC-A 8L, TO-71 6L, and SOT-23 6L package options.

< Back LSK389 Press Release Linear Systems Mar 17, 2023 Ultra-Low Noise, Monolithic Dual, N-Channel JFET NEWS RELEASE FOR INFORMATION CONTACT: Linear Systems, Inc. Sales Department Phone: (510) 490-9160 Email: sales@linearsystems.com Industry’s First 100% Noise Tested, Ultra-Low Noise, Monolithic Dual, N-Channel JFET FREMONT, CA – 01/21/2020 – Linear Systems announces the re-release of their most popular part, the LSK389 Series, Ultra-Low Noise, Monolithic Dual, N-Channel JFET, now 100% tested to meet or exceed noise specifications. The LSK389 is the lowest noise Junction Field Effect Transistor (JFET) in its class and has been used in ultra-high-end applications for over a decade. The LSK389 enables developers to create the lowest noise signal chains possible for sensors, professional audio equipment, and other applications. Linear Systems is releasing the LSK389 after developing the capability for 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. This testing capability – the only one in existence worldwide – ensures all LSK389s leaving the factory produce no burst (RTN or popcorn) noise and meet or exceed 1/f and broadband noise specifications. The LSK389, Ultra-Low Noise, Monolithic Dual, N-Channel JFET provides designers with a better-performing solution for obtaining tighter IDSS matching and better thermal tracking than using individual JFETs or non-monolithic dual JFETs. The part is an ideal combination of high transconductance, ultra-low noise, and relatively low input capacitance. The LSK389 is the lead part of Linear Systems’ family of low-noise JFETs. The LSK170 is the N-channel single version of the LSK389, and the LSJ74 is the P-channel counterpart to the LSK170. The N-channel dual LSK489 has slightly higher noise but lower input capacitance than the LSK389, and the LSJ689 is its P-channel dual counterpart. All Linear Systems’ JFET standard products have substantially lower noise than those made by other manufacturers and are marketed under the Improved Standard Products® trademark. Summary of Features: - Ultra-Low Noise: en = 1.3nV/√Hz (typ), f = 1.0kHz and NBW = 1.0Hz - Four grades of IDSS: 2.6-6.5mA, 6.0-12.0mA, 10.0-20.0mA, and 17-30mA, with an IDSS match of 10% - Tight Matching: IVGS1-2I = 15mV max - High Breakdown Voltage: BVGSS = 40V max - High Gain: Gfs = 20mS (typ) - Relatively Low Capacitance: 25pF (typ) - Available in surface mount SOIC 8L and thru-hole TO-71 6L packages Benefits: - Improved Signal Chain Noise Performance - Better Matching and Thermal Tracking Due to Unique Monolithic Interleaved Dual Design Construction - Better Performance for Battery-Operated Applications by Providing a Wide Output Swing Applications: - Ultra-Sensitive Sensor Applications - Audio Amplifiers and Preamps - Discrete Low-Noise Operational Amplifiers - Battery-Operated Audio Preamps - Audio Mixer Consoles - Sonic Imaging - Instrumentation Amplifiers - Microphones - Sonobuoys - Hydrophones - Chemical and Radiation Detectors Pricing and Availability: - 1,000+ pieces of the LSK389A SOIC 8L package are priced at $4.67 (USD) each. - 1,000+ pieces of the LSK389A TO-71 6L package are priced at $6.70 (USD) each.
