5.5 Audio ADC and Analog Inputs
5.5.1 MICBIAS and Microphone Preamplifier
The TLV320AIC3120 includes a microphone bias circuit which can source up to 4 mA of current, and is
programmable to a 2-V, 2.5-V, or AVDD level. The level can be controlled by writing to page 1 / register
46, bits D1–D0. This functionality is shown in Table 5-9.
