LA74309TT

Ordering number : ENA0903 www.DataSheet4U.com 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 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≤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 Ta≤85°C Conditions Ratings 4.0 50 -20 to +85 -55 to +150 Unit V mW °C °C Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.).
