- All functions are programmable via serial bus 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.
