Bare Die Product Detail: J202

N-Channel Low Noise Amp.:
High Gain N-Channel JFET amplifier. The J202 N-channel JFET is optimised for high gain and is particularly suitable for use in low power or high impedance amplifiers

This device features low cutoff voltage and high gain and is a direct replacement for Interfet, Intersil, Motorola, National / Fairchild, Philips, Vishay / Siliconix J202 or SST202.

Features:

High input impedance
Low cutoff voltage
Low noise

Applications:

Battery powered amplifiers
Audio pre-amplifiers
Infra-red detector amplifiers
