Controlled Audio Processor 28-Pin SO T/R

The TDA7442D is volume tone (bass and treble) balance (Left/Right) processors for quality audio applications in TV and Hi-Fi systems. It reproduces surround sound by using a programmable phase shifter. 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 BIPOLAR/CMOS Technology used, Low Distortion, Low Noise and DC stepping are obtained.
