STMicroelectronics TDA7449
The TDA7449 is a volume tone (bass and treble) ) SO20 ct(s Features rodu Input multiplexer – Two stereo inputs P – Selectable input gain for optimal adaptation te to different sources le One stereo output so Treble and bass control in 2.0 db steps b Volume control in 1.0 db steps - O Two speaker attenuators: ) – Two independent speaker controls in t(s 1.0 db steps to facilitate balance c – Independent mute function du All functions are programmable via serial bus balance (left/right) processor for quality audio applications in TV systems. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.
