EVALUATION KIT AVAILABLE MAX98300 Mono 2.6W Class D Amplifier General Description Features The MAX98300 mono 2.6W Class D amplifier provides S Industry-Leading Quiescent Current: 0.78mA at Class AB audio performance with Class D efficiency. 3.7V, 1.1mA at 5V This device offers five selectable gain settings (0dB, S Spread Spectrum and Active Emissions Limiting 3dB, 6dB, 9dB, and 12dB) set by a single gain-select S Five Selectable Gains input (GAIN). S Click-and-Pop Suppression Active emissions-limiting edge-rate and overshoot con- trol circuitry greatly reduces EMI. A patented filterless S Thermal and Overcurrent Protection spread-spectrum modulation scheme eliminates the need S Low-Current Shutdown Mode for output filtering found in traditional Class D devices. S Space-Saving Packages These features reduce application component count. 2mm x 2mm x 0.8mm, 8-Pin TDFN-EP The MAX98300 industry-leading 0.78mA at 3.7V (1.1mA 1.2mm x 1.2mm, 9-Bump WLP (0.4mm Pitch) 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.
