The BA3410AF is a playback / recording system preamplifier for mono tape recorders. It operates off a 3V supply.
The BA3410AF includes playback equalizer, mic, line, and recording amplifiers, an ALC circuit, and a playback / record-
ing control circuit. This construction allows switching between recording and playback modes with a single contact
switch, for smaller and simpler PCB designs.
When combined with a BTL power amplifier, almost all of the functions required for a 3V personal-memo or dictation
tape recorder are provided, allowing compact set designs.
