BA3402 Dual Channel Auto Reverse Tape Preamplifier

Audio ICs Dual-channel, auto-reverse tape preamplifier BA3402 The BA3402 is a dual preamplifier developed for auto-reverse car tape decks. An electronic switch on the chip switches between the forward and reverse heads, and this has the benefits of greater reliability, easier wiring, lower space requirements, and improved assembly efficiency when compared with conventional mechanical switches. The circuit is designed in such a way that coupling capacitors are not required. In addition to reduci.

BA3402 Features

* 1) Low noise (VNIN = 1.2µVrms). 2) High open loop gain (GVO = 85dB). 3) Reliable electronic switch on the chip. Head switching for both left and right channels is possible with the addition of one external switch circuit. 4) Input-side virtual-ground design means that input coupling capacitors are n
