Specifications of MAX98304EWL+T

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
19-5519; Rev 0; 9/10
The MAX98304 mono 3.2W 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 filterless spread-
spectrum modulation scheme eliminates the need for
output filtering found in traditional Class D devices. These
features reduce application component count.
The IC's 0.95mA at 3.7V (1.2mA at 5V) quiescent current
extends battery life in portable applications.
The IC is available in a 9-bump (1.0mm x 1.0mm) WLP
with 0.3mm pitch that is specified over the extended
-40NC to +85NC temperature range.
