MAX9879 Overview

MAX9879 The MAX9879 bines a high-efficiency stereo Class D audio power amplifier with a stereo capacitor-less DirectDrive® headphone amplifier. Maxim’s filterless class D amplifiers with active emissions limiting technology provide Class AB performance with Class D efficiency. The Class D power amplifier delivers up to 715mW from a 3.7V supply into an 8Ω load with 88% efficiency to extend battery life.

MAX9879 Key Features

  • Better than 9dB Margin Under EN 55022 Class B Limits with No Filter ponents
  • Low RF Susceptibility Design Rejects TDMA Noise from GSM Radios
  • Input Mixer with User Defined Input Mode
  • Stereo 715mW Speaker Output (RL = 8Ω, VDD = 3.7V)
  • Stereo 58mW Headphone Output (16Ω, VDD = 3.7V)
  • Low 0.04% THD+N at 1kHz (Class D Power Amplifier)
  • Low 0.018% THD+N at 1kHz (Headphone Amplifier)
  • 88% Efficiency (RL = 8Ω, POUT = 750mW)
  • 1.6Ω Analog Switch for Speaker Amplifier Bypass
  • High Speaker Amplifier PSRR (72dB at 217Hz)
