Class D audio subsystem provides high output power

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX9796 2.3-W, Class D audio subsystem.

The MAX9796 combines a high-efficiency, mono Class D amplifier; a DirectDrive stereo headphone amplifier; and a DirectDrive mono receiver amplifier.

By using Maxim's patented, DirectDrive architecture, the receiver and headphone amplifiers produce a ground-referenced output from a single supply, eliminating the need for large, DC-blocking capacitors. The MAX9796 employs Maxim's patented, active-emissions-limiting (AEL) circuitry and spread-spectrum-modulation technique, both of which are designed to reduce EMI and eliminate the output filters typically required by Class D amplifiers.

Applications include cell phones, portable media players (PMPs), handheld gaming consoles, and other applications in which high audio quality, output power, and efficiency are key requirements.

The MAX9796 is packaged in a 3mm x 3mm, 32-bump UCSP that is fully specified over the -40°C to +85°C extended temperature range.

Pricing: Starts at $1.67 (1000-up, FOB USA).
Availability: Now.
