LA74308LP ^{Monolithic Linear IC}
Audio Interface for DSC
Overview
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.)
• Electronic VOLUME (controlled by serial communication)
• LINE output (with SERIAL MUTE and MUTE transistor)
• STANDBY control
