TPA2015D1是一款高效D类音频功率放大器,具有电池跟踪SpeakerGuard AGC技术和集成的自适应升压转换器,可在低输出功率下提高效率。它可驱动高达2 W的8Ω扬声器(6%THD)。 TPA2015D1具有85%的典型效率,有助于延长播放音频时的电池寿命。
内置升压转换器为D类放大器产生5.5 V电源电压。与直接连接到电池的独立放大器相比,这提供了更响亮的音频输出。 SpeakerGuard TM AGC调节D类增益以限制电池电流并防止严重削波。
TPA2015D1具有集成的低通滤波器,可改善RF抑制并降低DAC带外噪声,增加信噪比(SNR)。
TPA2015D1采用节省空间1.954 mm×1.954 mm,0.5 mm间距DSBGA封装(YZH)。
