MAX98300

Mono 2.6W Class D Amplifier

General Description

The MAX98300 mono 2.6W Class D amplifier provides

Class AB audio performance with Class D efficiency.

This device offers five selectable gain settings (0dB,

3dB, 6dB, 9dB, and 12dB) set by a single gain-select

input (GAIN).

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 MAX98300 industry-leading 0.78mA at 3.7V (1.1mA

at 5V) quiescent current extends battery life in portable

applications.

The MAX98300 is available in an 8-pin TDFN-EP (2mm

x 2mm x 0.8mm) and a 9-bump (1.2mm x 1.2mm) WLP.

Both packages are specified over the extended -40NC to

+85NC temperature range.
