Product overview
Description
The TDA7449 is a volume tone (bass and treble) balance (left/right) processor for quality audio applications in TV systems. Selectable input gain is provided. A serial bus controls all functions.
The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.
Bipolar/CMOS technology used allows obtaining low distortion, low noise and DC stepping.
