The MAX98302 stereo 2.4W Class D amplifier provides
Class AB audio performance with Class D efficiency.
This device offers five selectable gain settings (6dB,
9dB, 12dB, 15dB, and 18dB) 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 MAX98302 industry-leading 1.65mA at 3.7V, 2.25mA
at 5V, quiescent current extends battery life in portable
applications.
The MAX98302 is available in a 14-pin TDFN-EP (3mm x
3mm x 0.75mm) package specified over the extended
-40NC to +85NC temperature range.
