TDA7316 equalizer equivalent, four bandsdigital controlled graphic equalizer.
of each band pass filter are reported: fo = center frequency Gv = gain/loss at the center frequency fo Gv = 20log(Av) Q= fo f2 − f1
where f2, f1 = 3dB Bandwidth limits. .
requiring higher number of external equalizer bands could be implemented by cascading 2 or more TDA7316 devices. In fact.
The TDA7316 is a monolithic, digitally controlled graphic equalizer realized in BiCMOS mixed technology. The stereo signal, before any filtering, can be atBLOCK DIAGRAM
