Overview

The TLV320AIC23B is a high-performance stereo audio codec designed for portable digital audio applications. It integrates a 24-bit sigma-delta ADC and DAC with support for sampling rates from 8 kHz to 96 kHz, making it suitable for high-fidelity recording and playback. The device features a highly flexible power management system and glueless interfacing to Texas Instruments McBSP-equipped DSPs.

Why Choose This Part

The codec provides exceptional audio performance with a 100-dB SNR DAC and flexible power modes, drawing as little as 15uA in shutdown. Its support for multiple serial protocols including I2S, SPI, and 2-wire makes it compatible with a wide range of host microcontrollers and DSPs.

Applications

Portable Digital Audio Players

Utilizes the high 100-dB SNR DAC for high-quality music playback in battery-powered devices.

Voice Over IP (VoIP) Handsets

Integrated microphone biasing and buffering simplifies the analog front-end for voice communication.

Digital Voice Recorders

The 90-dB SNR ADC provides clear 24-bit audio capture with low power consumption for extended recording time.

DSP-Based Audio Processing

Offers a seamless interface to TI DSPs via McBSP, supporting specialized 250/272 fs timing modes.

Getting Started

To evaluate this codec, engineers typically use the TLV320AIC23BEVM evaluation module. Configuration is performed through the control interface using standard I2C or SPI commands to set sampling rates, word lengths, and power management registers. Ensure the Master Clock (MCLK) frequency matches the desired sampling rate according to the datasheet tables for Normal or USB modes.
