<Analog Mixing Circuit for Speaker Output>
When AIN3 bit = “0”, DACS, MINS, LINS2 and RINS2 bits controls each path switch.
MIN path mixing gain is +4.43dB(typ)@SPKG bits = “00” & ALC bit = “0” when the external input resistance is 20k
.
LIN2, RIN2 and DAC pathes mixing gain is
1.59dB(typ)@SPKG bits = “00” & ALC bit = “0”.
