TA8155FG/FNG
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.
Features
