LA74308LP
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 communication • MIC AMP • MIC power supply incorporated (with built-in pull-up resistor) • ALC AMP • 4th order LPF + trap (compatible 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 communication) • LINE output (with SERIAL MUTE and MUTE
transistor) • STANDBY control...
