FOUR HIGH PASS CHANNELS ONE STEREO LOW PASS CHANNEL WITH GAIN CONTROL DIRECT MUTE PIN FULLY PROGRAMMABLE VIA I2C BUS DESCRIPTION The TDA7401 is an upgrade of the TDA7435 audioprocessor.
Due to a highly linear signal processing, using CMOS-switching techniques very low distortion and very low noise are obtained.
Second order high pass and low pass filters with programmable corner frequencies provide the loudspeaker equalization.
