ST TDA7439DS

音调处理器汽车音频，消费类音频2I²C7V ~ 10.2V

Overview

DescriptionThe TDA7439 is a volume, tone (bass, mid-rangeand treble) and balance (left/right) processor forhigh-quality audio applications in car-radio andHi-Fi systems. Selectable input gain is provided.All the functions are controlled by serial bus.The AC signal setting is obtained by resistornetworks and switches combined with operationalamplifiers.The TDA7439 employs BIPOLAR/CMOStechnology to provide low distortion, low noiseand DC stepping.

Features Input multiplexer– four stereo inputs– selectable input gain for optimal adaptationto different sources Single stereo output Treble, mid-range and bass control in 2-dBsteps Volume control in 1-dB steps Two speaker attenuators:– two independent speaker controls in 1-dBsteps for balance facility– independent mute function All functions are programmable via serial bus
