The TDA7442/42D is volume tone (bass and tre-
ble) balance (Left/Right) processors for quality au-
dio applications in TV and Hi-Fi systems.
It reproduces surround sound by using a program-
DESCRIPTION
mable phase shifter. 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 BIPOLAR/CMOS Technology used,
Low Distortion, Low Noise and DC stepping are
obtained.
