Overview
® TDA7449L LOW COST DIGITALLY CONTROLLED AUDIO PROCESSOR INPUT MULTIPLEXER - 2 STEREO INPUTS - SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTATION TO DIFFERENT SOURCES ONE STEREO OUTPUT VOLUME CONTROL IN 1.
0dB STEPS TWO SPEAKER ATTENUATORS: - TWO INDEPENDENT SPEAKER CONTROL IN 1.
0dB STEPS FOR BALANCE FACILITY - INDEPENDENT MUTE FUNCTION ALL FUNCTION ARE PROGRAMMABLE VIA SERIAL BUS DESCRIPTION The TDA7449L is a volume control and balance (Left/Right) processor for quality audio applications in TV systems.
Selectable input gain is provided.
Control of all the functions is accomplished by serial bus.
The AC signal setting is obtained by resistor netBLOCK DIAGRAM MUXOUTL 8 100K 9 100K G VOLUME 10 DIP20 ORDERING NUMBER: TDA7449L works and switches combined with operational amplifiers.
Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
