The TLV320AIC28 is a low-power, high-performance audio codec with 16/20/24/32-bit 95-dB stereo playback, mono record functionality at up to 48 ksps. Two microphone inputs include independent programmable bias voltages, built-in pre-amps, and hardware automatic gain control, with single-ended or fully-differential signal input capabilities.

The stereo 16-. headphones at 19 mW with a 3.3-V analog supply level.

The AIC28 offers a 12-bit measurement ADC and internal reference voltage. It includes an on-chip temperature sensor capable of reading 0.3°C resolution, as well as a battery measurement input capable of reading battery voltages up to 6 V, while operating at an analog supply as low as 3 V. The AIC28 is available in a 48-lead 7 x 7 mm QFN package.
