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.
The stereo 16-
headphone drivers on the AIC28 support
capless as well as ac-coupled output configurations. An
8-
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-
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-
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.
