MAX9704 - 10W Stereo/15W Mono Filterless Spread-Spectrum Class D Amplifiers

Download the MAX9704 datasheet PDF. This datasheet also covers the MAX9703 variant, as both devices belong to the same 10w stereo/15w mono filterless spread-spectrum class d amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX9703/MAX9704 mono/stereo Class D audio power amplifiers provide Class AB amplifier performance with Class D efficiency, conserving board space and eliminating the need for a bulky heatsink.

Using a Class D architecture, these devices deliver up to 15W while offering up to 78% efficiency.

Key Features

  • Filterless Class D Amplifier.
  • Unique Spread-Spectrum Mode Offers 5dB Emissions Improvement Over Conventional Methods.
  • Up to 78% Efficient (RL = 8Ω).
  • Up to 88% Efficient (RL = 16Ω).
  • 15W Continuous Output Power into 8Ω (MAX9703).
  • 2x10W Continuous Output Power into 8Ω (MAX9704).
  • Low 0.07% THD+N.
  • High PSRR (80dB at 1kHz).
  • 10V to 25V Single-Supply Operation.
  • Differential Inputs Minimize Common-Mode Noise.

19-3160; Rev 7; 3/06 www.DataSheet4U.com 10W Stereo/15W Mono, Filterless, Spread-Spectrum, Class D Amplifiers General Description The MAX9703/MAX9704 mono/stereo Class D audio power amplifiers provide Class AB amplifier performance with Class D efficiency, conserving board space and eliminating the need for a bulky heatsink. Using a Class D architecture, these devices deliver up to 15W while offering up to 78% efficiency. Proprietary and patent-protected modulation and switching schemes render the traditional Class D output filter unnecessary. The MAX9703/MAX9704 offer two modulation schemes: a fixed-frequency mode (FFM), and a spread-spectrum mode (SSM) that reduces EMI-radiated emissions due to the modulation frequency.
