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: VCCA≈3.0V)
Standby control (ICC≤10A)
