Status
Active: In Production.
Description
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.
The MAX9796 is available in a 36-bump UCSP™ (3mm x 3mm) package and is specified over the extended -40°C to +85°C temperature range.
