ZHCSGM5A August 2017 – November 2017 TLV320AIC3109-Q1
PRODUCTION DATA.
The TLV320AIC3109-Q1 includes a programmable microphone bias output voltage (MICBIAS), capable of providing output voltages of 2 V or 2.5 V (both derived from the on-chip, band-gap voltage) with a 4-mA output current drive. In addition, the MICBIAS can be programmed to be connected to AVDD directly through an on-chip switch, or powered down completely when not needed for power savings. This function is controlled by register programming in register 25, page 0.
