HT81293 - Boosted Class D Amplifier

General Description

HT81293, integrated with a boost converter, is a mono Class D audio amplifier that drives up to continuous 18W (10% THD+N, 1kHz) into 4ohm speaker from a Li-battery voltage.

Key Features

  • S Anti-Clipping Function (ACF) Spread spectrum technology Output Power 18W (VBAT=3.7V, RL=4Ω, THD+N=10%, fIN = 1kHz) 16W (VBAT=3.7V, RL=4Ω, THD+N=1%, fIN = 1kHz) Power Supply VBAT: 3.0V~12V High Efficiency Class H Boost Converter -Multiple boost voltages automatically adjust Class D audio amplifier (HT81293A) -Extends the playing time in battery supply.
