Order Codes Part Number TDA7463AD Package SSO20P The control of all the functions is accomplished by serial bus.
The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.
Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
2 DESCRIPTION The TDA7463AD is a volume tone (bass and treble) processor for quality audio applications in Low voltage supply portable systems.
Bass ALC (Automatic Level Control) function can be adjusted by a dedicated pin.
