TDA7317中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The TDA7317 is a monolithic, digitally controlled graphic equalizer realized in BiCMOS mixed technology. The stereo signal, before any filtering, can be attenuated up to -17.625dB in 0.375dB step. All the functions can be programmed via serial bus making easy to build a µP controlled system. Signal path is designedfor very low noise and distortion.
