The TPA301 is a bridge-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers are required. Operating with a 3.3-V supply, the TPA301 can deliver 250-mW of continuous power into a BTL 8- load at less than 1% THD+N throughout voice band frequencies. Although this device is characterized out to 20 kHz, its operation was optimized for narrower band applications such as cellular communications. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications, which is particularly important for small battery-powered equipment. This device features a shutdown mode for power-sensitive applications with a quiescent current of 0.15 µA during shutdown. The TPA301 is available in an 8-pin SOIC surface-mount package and the surface-mount PowerPAD MSOP, which reduces board space by 50% and height by 40%.

TPA301EVM — TPA301 评估模块 (EVM)
A low-voltage bridge-tied load (BTL) audio power amplifier capable of delivering 350-mW to the load. It is characterized at 3.3-V and 5-V, but will operate from 2-V to 5.5-V. To minimize power consumption, this device features a shutdown mode, holding IDD <0.15 µA. Package: 8-pin SOIC.
BOOSTXL-AUDIO — 音频信号处理 BoosterPack 插件模块
插入 LaunchPad™ 开发套件时，BOOSTXL-AUDIO Audio BoosterPack™ 插件模块可从麦克风采集音频输入并通过板载扬声器输出音频。也支持耳机输入和输出。这种音频输入/输出流让开发人员能够对随附 LaunchPad 开发套件上微控制器 (MCU) 的数字信号处理 (DSP) 和滤波功能进行实验。
可通过多种方案（可通过 BoosterPack 上的跳线进行选择）将扬声器连接到 LaunchPad 的 MCU：(1) 通过 SPI 将音频数据输出到音频 BoosterPack 上提供的 SPI DAC；(2) 直接连接到 LaunchPad MCU 上的 (...)
TIDM-VOICEBANDAUDIO — 使用 PWM DAC 的语音频带音频播放
基于定时器生成 PWM 的低成本音频输出，配合外部低通滤波器及放大级，可驱动耳机或扬声器。音频数据存储在板载 SPI 闪存中。提供了具有 LaunchPad 直通代码的 PC GUI，以加载包含音频数据的 SPI 闪存。
