Product Overview LA74309FA: Microphone Amplifier For complete documentation, see the data sheet Product Description LA74309FA is a microphone amplifier for digital still cameras that have mono audio recording. The analog signal processing for the recording of the digital still camera or other equipment can be easily composed, because the MIC power supply and the ALC circuit are built-in. Moreover, the regulator is built-in, therefore external regulator is unnecessary.
