Analog Mixing: Mono Input
When the PMBP bit is set to “1”, the mono input is powered-up. When the BEEPS bit is set to “1”, the input signal from
the MIN pin is output to Speaker-Amp. When the BEEPH bit is set to “1”, the input signal from the MIN pin is output to
Headphone-Amp. When the BEEPL 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 33, Table 34 and Table 35 show the typical
gain example at R
i
= 20k
.
This gain is in inverse proportion to R
