1 / 70 page BurrBrown Products from Texas Instruments FEATURES DESCRIPTION TLV320AIC31 SLAS497 – DECEMBER 2005 LOW POWER STEREO AUDIO CODEC FOR PORTABLE AUDIO/TELEPHONY • Stereo Audio DAC The TLV320AIC31 is a low-power stereo-audio codec with a stereo headphone amplifier, as well as multiple – 100 dB A Signal-to-Noise Ratio inputs and outputs, programmable in single-ended or – 16/20/24/32-Bit Data fully-differential configurations. Extensive – Supports Rates From 8 kHz to 96 kHz register-based power control is included, enabling – 3D/Bass/Treble/EQ/De-Emphasis Effects stereo 48-kHz DAC playback as low as 14 mW from a 3.3-V analog supply, making it ideal for portable, • Stereo Audio ADC battery-powered audio and telephony applications. – 92 dB A Signal-to-Noise Ratio The record path of the TLV320AIC31 contains – Supports Rates From 8 kHz to 96 kHz integrated microphone bias, digitally-controlled • Six Audio Input Pins stereo-microphone pre-amp, and automatic gain – Two Stereo Differential/Single-Ended Inputs control (AGC), with mix/mux capability among the multiple analog inputs. The playback path includes • Six Audio Output Drivers mix/mux capability from the stereo DAC and selected – Stereo 8- Ω, 500 mw/Channel Speaker Drive inputs, through programmable volume controls, to the Capability various outputs. – Stereo Fully-Differential or Single-Ended The TLV320AIC31 contains four high-power output Headphone Drivers drivers as well as two fully differential output drivers. – Fully Differential Stereo Line Outputs The high-power output drivers are capable of driving a variety of load configurations, including up to four • Low Power: 14-mW Stereo, 48-kHz Playback channels of single-ended 16- Ω headphones using With 3.3-V Analog Supply ac-coupling capacitors, or stereo 16- Ω headphones in • Programmable Input/Output Analog Gains a cap-less output configuration. In addition, pairs of • Automatic Gain Control (AGC) for Record drivers can be used to drive 8- Ω speakers in a BTL configuration at 500 mW per channel. • Programmable Microphone Bias Level • Programmable PLL for Flexible Clock The stereo audio DAC supports sampling rates from 8 kHz to 96 kHz and includes programmable digital Generation filtering in the DAC path for 3D, bass, treble, • I2C Control Bus midrange effects, speaker equalization, and • Audio Serial Data Bus Supports I2S, de-emphasis for 32 kHz, 44.1 kHz, and 48 kHz rates. Left/Right-Justified, DSP, and TDM Modes The stereo-audio ADC supports sampling rates from 8 kHz to 96 kHz and is preceded by programmable • Extensive Modular Power Control gain amplifiers providing up to +59.5 dB analog gain • Power Supplies: for low-level microphone inputs. – Analog: 2.7 V – 3.6 V The serial control bus supports the I2C protocol, while – Digital Core: 1.525 V – 1.95 V the serial-audio data bus is programmable for I2S, – Digital I/O: 1.1 V – 3.6 V left/right justified, DSP, or TDM modes. A highly programmable PLL is included for flexible clock • Available Packages: 5 × 5 mm, 32-Pin QFN 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.
