Bare Die Product Detail: LSJ74A

P-Channel Low Noise Amp.:
Ultra-low noise single P-Channel JFET. The LSJ74A is optimised for low noise audio amplifier applications and is complimentary to LSK170 N-Channel series.

This device features ultra-low noise, high gain and high input impedance with low capacitance. LSJ74A is an improved direct replacement for Toshiba 2SJ74 with higher precision I_DSS grading.

Features:

Ultra-low noise e_n 0.9nV/√Hz (TYP)
High gain G_fs 22mS (TYP)
High input impedance I_G 1nA
Low capacitance C_RSS 32pF (TYP)

Applications:

Low noise audio amplifiers
Input stages of EQ and M.C. head amplifier
