TPA3123D2

具有 SE 输出的 25W 立体声 D 类音频功率放大器 TPA3123

The is a 25-W per channel efficient, Class-D audio power amplifier for driving stereo speakers in a single-ended configuration or a mono speaker in a bridge-tied-load configuration. The TPA3123D2 can drive stereo speakers as low as 4 . The efficiency of the TPA3123D2 eliminates the need for an external heat sink when playing music.

The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36 dB.
