Analog Mixing: Mono Input (MIN pin)
When AIN3 bit = “0”, MIN pin is used as mono input for analog mixing. When the PMMIN bit is set to “1”, the mono
input is powered-up. When the MINS bit is set to “1”, the input signal from the MIN pin is output to Speaker-Amp. When
the MINH bit is set to “1”, the input signal from the MIN pin is output to Headphone-Amp. When the MINL bit is set to
“1”, the input signal from the MIN pin is output to the stereo line output amplifier. The external resister Ri adjusts the
signal level of MIN input. Table 45, Table 47 and Table 48 show the typical gain example at R
i
= 20k
.
This gain is in
inverse proportion to R
