HT81697 Overview
HT81697, integrated with a boost converter, is a mono Class D/Class AB audio amplifier that drives up to continuous 28W (10% THD+N, 1kHz) into 4ohm speaker from two Li-batteries in series boosted to 15.5V. HT81697 integrates a boost converter that generates a power supply for the power amplifier, so that a higher power can be achieved. The output voltage of boost converter can be configured by external resistors.
