DESCRIPTION

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.

Stereo 16-ꢀ Headphone Amplifier With

Capless Output Option

400-mW 8-ꢀ Audio Power Amp With Direct

Battery Supply Connection

32-ꢀ Differential Earpiece Driver

The stereo 16-Ω headphone drivers on the AIC28 support

capless as well as ac-coupled output configurations. An

8-Ω BTL differential speaker driver provides up to 400 mW

of power and 98-dB SNR, while a differential driver is also

available for driving a 32-Ω speaker or telephone earpiece.

A programmable digital audio effects processor enables

bass, treble, midrange, or equalization playback

processing. The digital audio data format is programmable

to work with popular audio standard protocols (I²S, DSP,

left/right justified) in master or slave mode, and also

includes an on-chip programmable PLL for flexible clock

generation capability. Highly configurable software power

control is provided, enabling 48 ksps stereo audio

playback to 16-Ω headphones at 19 mW with a 3.3-V

analog supply level.

Direct Battery Measurement Accepts Up to

6-V Input

On-Chip Temperature and Auxiliary Input

Measurement

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.
