BEEP Input
When the PMBPM bit is set to “1”, mono beep input is powered up. And when the BPMHP bit is set to “1”, the signal
from the BEEP pin is input to Headphone-amp. When the BPMSP bit is set to “1”, the signal from the BEEP pin is input
to Speaker output. The external resisters Ri adjust the signal level of each BEEP input that are mixed to Headphone and
Speaker outputs.
The signal from the BEEP pin is mixed to the Headphone-amp through a –20dB gain stage. The signal from the BEEP pin
is mixed to the Speaker-amp without gain. The internal feedback resistance is 20k
Ω
±
30%. When BPMT bit is “1”, BEEP
input is muted.
When INBP bit is “1”, BEEP pin becomes IN2 pin.
