Monolithic Linear IC

Microphone Amplifier for

Digital Still Camera

LA74309TT

Overview

LA74309TT 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 IC is unnecessary.

Features

• Microphone (MIC) amplifier (+20dB)

• MIC power supply with built-in pull-up resistor

• Automatic level control (ALC) amplifier (output level=-1dBV≈2.5Vpp)

• 3rd order LPF (fc=11kHz)

• 3.3V regulator (internal supply voltage: V A≈3.0V)

• Standby control (I ≤10µA)
