Mono 2W Class D Amplifier

MAX9830

General Description

Features

The MAX9830 mono 2W Class D amplifier provides

Class AB audio performance with Class D efficiency.

o Industry-Leading Quiescent Current: 1.6mA at 5V,

1.2mA at 3.6V

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.

o Spread Spectrum and Active Emissions Limiting

o Passes EMI Limit Unfiltered with Up to 24in

(61cm) of Speaker Cable

o Click-and-Pop Suppression

o Thermal and Overcurrent Protection

o Low 0.5µA Current Shutdown Mode

The MAX9830’s industry-leading 1.6mA at 5V, 1.2mA at

3.6V, quiescent current extends battery life in portable

applications.

o Space-Saving, 2mm x 2mm x 0.8mm, 8-Pin TDFN

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.
