MAXIM MAX9796 2.3W High-Power Class D Audio Subsystem with DirectDrive Headphone Amplifiers handbook
Update: 28 September, 2023
The MAX9796 combines a high-efficiency Class D, mono audio power amplifier with a mono DirectDrive™ receiver amplifier and a stereo DirectDrive headphone amplifier. Maxim’s 3rd-generation, ultra-low EMI, Class D audio power amplifiers provide Class AB performance with Class D efficiency. The MAX9796 delivers 2.3W into a 4Ω load from a 5V supply and offers efficiencies up to 80%. Active emissions limiting circuitry and spread-spectrum modulation greatly reduce EMI, eliminating the need for output filtering found in traditional Class D devices. The MAX9796 features a fully differential architecture, a full-bridged output, and comprehensive click-and-pop suppression. The device utilizes a flexible, user-defined mixer architecture that includes an input mixer, volume control, and output mixer. All controls are done through an I2C interface. The mono receiver amplifier and stereo headphone amplifier use Maxim’s DirectDrive architecture, that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, space, and component height.
