HT6881 - 4.7W Anti-Cut Top Mono Audio Power Amplifier

Download the HT6881 datasheet PDF. This datasheet also covers the HT6881-1 variant, as both devices belong to the same 4.7w anti-cut top mono audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

HT6881 is a Low-EMI, Anti-Clipping, filter-less mono Class D audio power amplifier IC with maximum output power of 4.7W (6.5V power supply, 4Ω load, 10% THD+N).

It has a high efficiency with class AB amplifier performance.

Key Features

  • Anti-Clipping Function (ACF) which detects and suppresses output signal clippings due to the over level inputs of music or voice signals. The ACF function also can adapt the output clippings caused by power supply voltage down in battery.
