Overview
Monolithic Linear IC
Audio Interface for DSC
The LA74308LP is a SPEAKER AMP and MIC AMP built-in audio interface for DSC. It incorporates an 8/16kHz trap and supports CODECs with a sampling rate of 8kHz or 16kHz.
Features
- Three-wire type SERIAL munication
- MIC AMP
- MIC power supply incorporated (with built-in pull-up resistor)
- ALC AMP
- 4th order LPF + trap (patible with REC/PB changeover, trap frequency selectable from 8kHz and 16kHz)
- SPEAKER AMP (The BEEP signal can be mixed.), with electronic VOLUME (controlled by serial munication)
- LINE output (with SERIAL MUTE and MUTE transistor)
- STANDBY...
