TDA7317

® TDA7317 FIVE BANDS DIGITAL CONTROLLED GRAPHIC EQUALIZER 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 DESCRIPTION The TDA7317 is a monolithic, digitally controlled graphic equalizer realized in BiCMOS mixed technology. The stereo signal, before any filtering, can be atBLOCK DIAGRAM SDIP30 ORDERING NUMBER: TDA7317 tenuated 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 designed for very low noise and distortion.
