Overview
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 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)
• 3V regulator (At the time of VCC=3.3V, internal supply voltage: VCCA≈3.0V)
• Standby control (ICC≤10μA)

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
