MAX98304 Mono 3.2W Class D Amplifier General Description 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 control circuitry greatly reduces EMI. A filterless spreadspectrum 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.
