Analog Mixing : Mono Input
When the PMBP bit is set to “1”, the mono input is powered-up. 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 35 and Table 36
show the typical gain example at R
i
= 20k
Ω.
This gain is in inverse proportion to R
i
.
