General Description

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.

Key Features

  • ion (ACF).
  • Spread spectrum technology.
  • Output Power 28W (VBAT=7.2V, RL=4Ω, THD+N=10%, PVDD = 15.5V, fIN = 1kHz) 22W (VBAT=7.2V, RL=4Ω, THD+N=1%, PVDD = 15.5V, fIN = 1kHz) 16.5W (VBAT=3.7V, RL=4Ω, THD+N=10%, PVDD = 12V, fIN = 1kHz) 12.8W (VBAT=3.7V, RL=4Ω, THD+N=1%, PVDD = 12V, fIN = 1kHz).
  • Power Supply VBAT: 3.0V~12V.
  • Integrates High Efficiency Boost Converter -Adjustable voltage by external resistor -Adjustable switch peak current limit to avoid over-pulling on battery current.
