HT862 Features

* Automatic Gain Control (AGC) with Battery Tracking and Limiter function - Battery Tracking: automatically reduce system gain to extend battery life when the battery voltage is low - Limiter: adjusts the amplifier gain to prevent heavy clipping Integrated Adaptive Boost Converter - Increases efficien
