Stereo 3.7W Class D Amplifier General Description The MAX98306 stereo 3.7W 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 combined with a filterless spread-spectrum modulation scheme (SSM) provide excellent EMI perfor- mance while eliminating the need for output filtering found in traditional Class D devices. These features reduce application component count. The IC's 2.0mA quiescent current with a 3.7V supply extends battery life in portable applications. The IC is available in a 14-pin TDFN (3mm x 3mm x 0.75mm) package specified over the extended -40NC to +85NC temperature range. Applications Features S Output Power 3.7W at 3I, 10% THD, 1.7W at 8I, 10% THD, with 5V Supply S Passes EMI Limit Unfiltered with Up to 12in of Speaker Cable S High 83dB PSRR at 217Hz S Spread-Spectrum Modulation and Active Emissions Limiting S Five Pin-Selectable Gains S Excellent Click-and-Pop Suppression S Thermal and Overcurrent Protection S Low-Current Shutdown Mode S Space-Saving, 3mm x 3mm x 0.75mm, 14-Pin TDFN 19-5919; Rev 0; 6/11 +Denotes a lead(Pb)-free/RoHS-compliant package.
