General 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 pro-
duces 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.
