TDA7318 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
The TDA7318 is a volume, tone (bass and treble) balance (Left/Right) and fader (front/rear) processor for quality audio applications in car radio and Hi-Fi systems.
Selectable input gain is provided. Control is accomplished by serial I2C bus microprocessor interface. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.

INPUT MULTIPLEXER:
- 4 STEREO INPUTS
- SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTION TO DIFFERENT SOURCES
INPUT AND OUTPUT FOR EXTERNAL EQUALIZER OR NOISE REDUCTION SYSTEM
VOLUME CONTROL IN 1.25dB STEPS
TREBLE AND BASS CONTROL
FOUR SPEAKER ATTENUATORS:
- 4 INDEPENDENT SPEAKERS CONTROL IN 1.25dB STEPS FOR BALANCE AND FADER FACILITIES
- INDEPENDENT MUTE FUNCTION
ALL FUNCTIONS PROGRAMMABLE VIA SERIAL I2C BUS
