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-
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 distor-
tion.
