FPA6101 - 2.4W Stereo Audio Power Amplifier and Headphone Driver

Datasheet Summary

Description

The FPA6101 is a monolithic integrated circuit combining a stereo power amplifier with a stereo capacitor-less headphone amplifier in a space and cost efficient package.

The headphone amplifier is ground-referenced to eliminate the output capacitors saving money and PCB space.

Features

  • Operating Voltage: VDD, PVDD, CVDD = 4.5V to 5.5V HVDD = 3.0V to 3.6V.
  • No Output Capacitors Required for Headphones.
  • Supply Current.
  • IDD = 12mA at VDD = 5V (Amplifier Mode).
  • IDD = 10mA at VDD = 5V (Headphone Mode).
  • Low Shutdown Current.
  • Meets VISTA Requirements.
  • Low Distortion AMP mode.
  • THD+N = 56dB, RL = 4Ω, PO = 1.5W.
  • THD+N = 64dB, RL = 8Ω, PO = 0.9W HP mode.
  • THD+N = 73dB, RL = 16Ω, PO = 125mW.
  • THD+N = 77dB, R.
