Tape & Reel

– TWO INDEPENDENT SPEAKER CONTROL

IN 1.0dB STEPS FOR BALANCE FACILITY

– -INDEPENDENT MUTE FUNCTION

Selectable input gain is provided. Control of all the

functions is accomplished by serial bus.

■ ALL FUNCTION ARE PROGRAMMABLE VIA

SERIAL BUS

The AC signal setting is obtained by resistor net-

works and switches combined with operational

amplifiers.

2 DESCRIPTION

The TDA7438 is a volume tone (bass, middle and

treble) balance (Left/Right) processor for quality

audio applications in car-radio and Hi-Fi systems.

Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and DC stepping are

obtained.
