Figure 32. Passive Analog Bypass Mode Configuration
The TLV320AIC3107 includes a programmable microphone bias output voltage (MICBIAS), capable of providing
output voltages of 2.0 V or 2.5 V (both derived from the on-chip bandgap voltage) with 4-mA output current drive.
In addition, the MICBIAS may be programmed to be switched to AVDD directly through an on-chip switch, or it
can be powered down completely when not needed, for power savings. This function is controlled by register
programming in Page-0/Reg-25.
