NOLOGY

DESCRIPTION

The TDA7317 is a monolithic, digitally controlled

graphic equalizer realized in BiCMOS mixed technol-

ogy. The stereo signal, before any filtering, can be at-

tenuated up to -17.625dB in 0.375dB step.

All the functions can be programmed via serial

bus making easy to build a

µPcontrolled system.

Signal path is designed for very low noise and distor-

tion.
