Description
Mono 2w Class D Amplifier
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX9830 mono 2W Class D amplifier provides
Class AB audio performance with Class D efficiency.
Active emissions limiting edge rate and overshoot con-
trol circuitry greatly reduces EMI. A patented filterless
spread-spectrum modulation scheme eliminates the
need for output filtering found in traditional Class D
devices. These features reduce application component
count.
The MAX9830’s industry-leading 1.6mA at 5V, 1.2mA at
3.6V, quiescent current extends battery life in portable
applications.
The MAX9830 is available in an 8-pin TDFN (2mm x
2mm x 0.8mm) and is specified over the extended
-40°C to +85°C temperature range.
19-4806; Rev 0; 8/09
