MAX9879 Datasheet Stereo Class D Audio Subsystem

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4436; Rev 0; 2/09 KIT ATION EVALU E L B A AVAIL Stereo Class D Audio Subsystem with DirectDrive Headphone.

General Description

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.

Key Features

  • Better than 9dB Margin Under EN 55022 Class B Limits with No Filter Components.
  • 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).
