FAB3103 - 2.3 Watt Class-D Audio Amplifier

Datasheet Summary

Description

The FAB3103 is a mono Class-D audio amplifier with an integrated boost regulator that achieves high output audio over a power supply range of 2.5V to 5.2V.

Features

  • High Output, Low Distortion Class-D Mono Speaker Amplifier o 2.3W into 8Ω from 3.6V Supply (10% THD+N) o 1.85W into 8Ω from 3.6V Supply (1% THD+N) o 0.01% THD+N into 8Ω (100mW).
  • High-Efficiency Boost Regulator Provides Higher Output Power Over Li-Ion Battery Voltages o 85% Total Efficiency (3.6V, 8Ω, PO = 1.0W).
  • Adaptive Boost Shutdown at Lower Output Power Increases Efficiency and Reduces Quiescent Current Consumption: o IDD = 2.7mA from 3.6V Supply.
  • Automatic Gain Control.
