TDA7316 Datasheet (ST Microelectronics) - FOUR BANDSDIGITAL CONTROLLED GRAPHIC EQUALIZER

TDA7316, FOUR BANDSDIGITAL CONTROLLED GRAPHIC EQUALIZER

The TDA7316 is a monolithic, digitally controlled graphic equalizer realized in BiCMOS mixed technology.

The stereo signal, before any filtering, can be atBLOCK DIAGRAM tenuated down to -17.625dB in 0.375dB step.

All the functions can be programmed via serial bus making easy to build a µP controlle

TDA7316 Features

* of each band pass filter are reported: fo = center frequency Gv = gain/loss at the center frequency fo Gv = 20log(Av) Q= fo f2
