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.

■ VOLUME CONTROL IN 0.375dB STEP
■ FIVE BANDS STEREO GRAPHIC EQUALIZER
■ CENTER FREQUENCY, BANDWIDTH, MAX BOOST/CUT DEFINED BY EXTERNAL COMPONENTS
■ ±14dB CUT/BOOST CONTROL IN 2dB/STEP
■ ALL FUNCTIONS PROGRAMMABLE VIA SERIALBUS
■ VERY LOW DISTORTION
■ VERY LOW NOISE AND DC STEPPING BY USE OF A MIXED BIPOLAR/CMOS TECHNOLOGY
