Micross Announces Global Availability of New Low-Cost, Low-Noise LS844 Series Dual JFET Linear Systems for High-Performance Applications

MELVILLE, NY, August 31, 2022 /PRNewswire/ — Micross Components, Inc. (“Micross”), a leading global supplier of mission-critical microelectronic components and services for high-reliability aerospace, defense, space, medical and industrial applications, is pleased to announce the worldwide availability of Linear Systems’ new high-performance, low-cost, low-noise LS844 JFET. As an authorized worldwide distributor for Linear Systems, Micross is excited to provide the latest evolution of this classic dual JFET first introduced by Linear Systems over 20 years ago, with immediate wide-scale availability and pricing in big volume. The company has refined the part’s design and manufacturing processes to improve its low-noise, matching, and common-mode rejection ratio qualities, while maintaining linearity and other characteristics sought by circuit designers. audio and others.

The LS844 is a low-noise junction field-effect transistor (JFET) ideal for precision, high-end audio, sensor, and discrete op-amp applications. It features a unique design construction of interleaving the two JFETs on the same piece of silicon to provide excellent matching and thermal tracking, as well as a low-noise profile having near-zero popcorn noise and noise distortion. weaker intermodulation.

The LS844, low-noise, dual-monolithic, N-channel JFET provides designers with a higher-performance solution to achieve 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, low noise (2.5 nV/√Hz typical at f=1 kHz), and very low input capacitance (3pF typical CISS). Sometimes it is necessary to cascode a JFET in order to achieve higher bandwidth by eliminating the Miller effect multiplication of the gate-drain capacitance, even in cases where Crss is already low like with the LS844.

Applications for the LS844 include broadband differential amplifiers, high CMMR front ends, temperature compensated single-ended input amps, tight tracking current sources, low-jitter high-speed comparators, impedance converters, acoustic sensors, piezoelectric sensors, sensitive charge amplifiers, and much more. .

“Through our long-standing partnership with Micross Components, we are excited to provide circuit designers with this next-generation dual JFET technology, offering lower noise with improved common-mode match ratio and rejection qualities, while maintaining the linearity and other characteristics sought after by audio and other circuit designers,” Paul NortonDirector of Customer and Distributor Engagement at Linear Integrated Systems.

“Linear Systems’ next-generation dual JFET technology further strengthens our broad portfolio of best-in-class, high-performance electronics solutions, allowing designers to further optimize their devices,” said Mark Zack, senior vice president of Micross Components, Die & Wafer Services. “We are excited to offer the new LS844 Dual JFET series worldwide, with immediate wide availability.”
