ROHM Semiconductor BA3410AF
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 / recording control circuit.Audio ICs 3V recording / playback system preamplifier BA3410AF It operates off a 3V supply. 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. FApplications 3V personal-memo tape recorders FFeatures 1) Internal recording / playback mode switch requires just a single contact switch. 2) Recording monitoring is possible. 3) Direct-head coupling is possible for playback. 4) Low power dissipation (recording: 4.8mA, playback: 3.8mA). 5) 16-pin SOP package allows compact set designs.
