The device includes extensive register-based power control is included, thus enabling stereo 48-k Hz DAC playback as low as 14 m W from a 3.3-V analog supply, making the device ideal for portable batterypowered audio and telephony applications. The record path of the TLV320AIC3104 contains integrated microphone bias, digitally controlled stereo microphone preamplifier, and automatic gain control (AGC), with mix/mux capability among the multiple analog inputs.
