HT8731 Overview
HT8731, integrated with adaptive class H boost converter, is a mono Class D audio amplifier that drives up to continuous 6W (<1% THD+N, 20-20kHz full band) into 4ohm speaker from a Li-battery voltage. It also integrates Class AB amplifier. The built-in Class H boost converter generates a Class D amplifier supply rail with a max voltage of 8.0V.
HT8731 Key Features
- High Efficiency Class H Boost Converter
- Multiple boost voltages automatically adjust Class D audio amplifier
- Extends the playing time in battery supply
HT8731 Applications
- Adjustable switch peak current limit to avoid over-pulling on battery current
