TDA7463AD

Package

SSO20P

The control of all the functions is accomplished by

serial bus.

The AC signal setting is obtained by resistor net-

works and switches combined with operational

amplifiers.

Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and DC stepping are

obtained.

DESCRIPTION

The TDA7463AD is a volume tone (bass and tre-

ble) processor for quality audio applications in Low

voltage supply portable systems.

Bass ALC (Automatic Level Control) function can

be adjusted by a dedicated pin.
