 Analog Mixing: Mono Input
When AIN3 bit = â0â, MIN pin is used as mono input for analog mixing. When the PMMIN bit is set to â1â, the mono
input is powered-up. When the MINS bit is set to â1â, the input signal from the MIN pin is output to Speaker-Amp. When
the MINH bit is set to â1â, the input signal from the MIN pin is output to Headphone-Amp. When the MINL bit is set to
â1â, 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 41, Table 43 and Table 44 show the typical gain example at Ri = 20kâ¦. This gain is in
inverse proportion to Ri .
