The TLV320ADC3101 device is a low-power, stereo audio analog-to-digital converter (ADC) supporting sampling rates from 8 kHz to 96 kHz with an integrated programmable-gain amplifier providing up to 40-dB analog gain or AGC. A programmable miniDSP is provided for custom audio processing. Front-end input coarse attenuation of 0 dB, –6 dB, or off, is also provided. The inputs are programmable in a combination of single-ended or fully differential configurations. Extensive register-based power control is available via an I2C interface, enabling mono or stereo recording. Low power consumption makes the TLV320ADC3101 ideal for battery-powered portable equipment.

The AGC programs to a wide range of attack (7 ms to 1.4 s) and decay (50 ms to 22.4 s) times. A programmable noise-gate function is included to avoid noise pumping. Low-latency IIR filters optimized for voice and telephony are available, as well as linear-phase FIR filters optimized for audio. Programmable IIR filters are also available and may be used for sound equalization, or to remove noise components. The audio serial bus can be programmed to support I2S, left-justified, right-justified, DSP, PCM, and TDM modes. The audio bus may be operated in either master or slave mode.

A programmable integrated PLL is included for flexible clock generation and provides support for all standard audio rates from a wide range of available MCLKs, varying from 512 kHz to 50 MHz, including the most popular cases of 12-MHz, 13-MHz, 16-MHz, 19.2-MHz, and 19.68-MHz system clocks.

参考设计

TIDA-01589 — 具有降噪和回声消除功能的高保真、近场双向音频参考设计

人机交互需要声学接口以提供全双工免提通信。在免提模式中,来自扬声器的远端或近端音频信号的一部分耦合至麦克风。此外,在噪声环境中,除了有用的近端音频信号之外,麦克风还会捕获环境噪声。捕获的多麦克风音频信号被声学背景噪声以及回声信号破坏,回声信号会显著降低所需信号的可懂度,并限制后续音频处理系统的性能。此参考设计所展示的双麦克风用于通过立体声 ADC 实现音频输入,通过低功耗 DSP 执行降噪、声学回声消除和其他音频质量增强算法。此参考设计还采用了 TI 的智能放大器技术,从而可通过微型扬声器实现高质量、高 SPL 的音频输出。
