LA74309TT Datasheet Monolithic Linear Ic Microphone Amplifier

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : ENA0903 .. Monolithic Linear IC LA74309TT Overview Microphone Amplifier for Digital Still Camera 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 posed, because the MIC power supply and the ALC circuit are built-in. Moreover, the regulator is built-in, therefore external regulator IC is unnecessary.

Key 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≤10µA) Specifications Maximum Ratings at Ta=25°C Parameter Maximum power supply voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC max Pd max Topr Tstg T.
