LOW-POWER STEREO AUDIO CODEC FOR PORTABLE AUDIO/TELEPHONY
23
Stereo Audio DAC:
–
100-dB (A-Weighted) Signal-to-Noise Ratio
The TLV320AIC31 is a low-power stereo audio codec
with a stereo headphone amplifier, as well as multiple
–
16-/20-/24-/32-Bit Data
inputs and outputs, programmable in single-ended or
–
Supports Rates From 8 kHz to 96 kHz
fully-differential
configurations.
Extensive
–
3D/Bass/Treble/EQ/De-Emphasis Effects
register-based power control is included, enabling

92-dB (A-Weighted) Signal-to-Noise Ratio
supply, making it ideal for portable, battery-powered
–
Supports Rates From 8 kHz to 96 kHz
audio and telephony applications.
Six Audio Input Pins:
The record path of the TLV320AIC31 contains

Stereo Fully-Differential or Single-Ended
inputs, through programmable volume controls to the
various outputs.
Headphone Drivers
–
Fully Differential Stereo Line Outputs
The TLV320AIC31 contains four high-power output
drivers as well as two fully differential output drivers.
Low Power: 14-mW Stereo, 48-kHz Playback
The high-power output drivers are capable of driving

analog-to-digital
converter
(ADC)
Power Supplies:
supports sampling rates from 8 kHz to 96 kHz and is
–
Analog: 2.7 V to 3.6 V
preceded by programmable gain amplifiers providing
–
Digital Core: 1.65 V to 1.95 V
up to +59.5 dB analog gain for low-level microphone
inputs.
–
Digital I/O: 1.1 V to 3.6 V
Available Packages: 5-mm × 5-mm,
The serial control bus supports the I2C protocol, while
the serial-audio data bus is programmable for I2S,
32-Pin QFN
left-/right-justified, DSP, or TDM modes. A highly
programmable PLL is included for flexible clock
generation and support for all standard audio rates
from a wide range of available MCLKs, varying from
512 kHz to 50 MHz, with special attention paid to the
most popular cases of 12-MHz, 13-MHz, 16-MHz,
19.2-MHz, and 19.68-MHz system clocks.
