TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic

TA8155FG,TA8155FNG

REC / PB System Dual Pre−amplifier (1.5 / 3V USE)

The TA8155FG and TA8155FNG are REC / PB system dual pre

amplifier ICs, which are developed for low voltage operation (1.5 /

3V use). These are especially suitable for a stereo headphone

cassette player.
