S4308 Datasheet Audio IC

Manufacturer: AUK (Kodenshi AUK Group)

Datasheet Details

The S4308 is a single preamplifier IC with built-in ALC circuit, and has been designed for use in stereo radio-cassette recorders and tape recorders.

The preamplifier has high gain and low distortion, and can be directly coupled to the tape head without coupling capacitors.

This prevents tape head magnetization and pop noise generation.

Built-in ALC rectifier diode.
Wide operating power supply voltage range (VCC=5V to 14V).
Low current dissipation (IQ=2.1mA).
High gain (GVO=80dB).
Low distortion (THD=0.1%).
Low noise (VNIN=1μVrms).
Input coupling capacitor unnecessary.
Power-on mute circuit.
ALC dynamic range can be varied by the addition of an external input resistor. ◈.
