General Description

The LM4865 is a mono bridged audio power amplifier with DC voltage volume control. The LM4865 is capable of delivering 750mW of continuous average power into an 8 load with less than 1% THD when powered by a 5V power supply. Switching between bridged speaker mode and headphone (single ended) mode is accomplished using the headphone sense pin. To conserve power in portable applications, the LM4865's micropower shutdown mode (IQ = 0.7µA, typ) is activated when less than 300mV is applied to the DC Vol/SD# pin.

Boomer audio power amplifiers are designed specifically to provide high power audio output while maintaining high fidelity. They require few external components and operate on low supply voltages.

Features

  • DC voltage volume control
  • Headphone amplifier mode
  • "Click and pop" suppression
  • Shutdown control when volume control pin is low
  • Thermal shutdown protection

Key Specification

PO at 1.0% THD+N into 8 SO, micro SMD 750mW (typ)
PO at 10% THD+N into 8 SO, micro SMD 1W (typ)
Shutdown current0.7µA(typ)
Supply voltage range2.7V to 5.5V

Applications

  • GSM phones and accessories, DECT, office phones
  • Hand held radio
  • Other portable audio devices
