3 说明

TPA2015D1 是一款高效的 D 类音频功率放大器，采用电池跟踪 SpeakerGuard™ AGC 技术，并具有集成式自适应升压转换器，可在低输出功率下提高效率。它可为 8Ω 扬声器提供高达 2W 功率 (6% THD)。TPA2015D1 的典型效率为 85%，可在播放音频时帮助延长电池寿命。

内置的升压转换器为 D 类放大器提供 5.5V 的电源电压。相比直接连接电池供电的独立放大器，这款放大器可提供更加响亮的音频输出。SpeakerGuardTM AGC 可调节 D 类放大器增益，从而限制电池电流并防止严重削波。

TPA2015D1 具有一个集成式低通滤波器，可改善射频抑制性能并减少 DAC 的带外噪声，从而提高信噪比 (SNR)。

TPA2015D1 采用节省空间的 1.954mm × 1.954mm、0.5mm 间距 DSBGA 封装 (YZH)。
