19-4806; Rev 0; 8/09 KIT ATION EVALU E L B AVAILA www.DataSheet4U.com Mono 2W Class D Amplifier General Description Features o Industry-Leading Quiescent Current: 1.6mA at 5V, 1.2mA at 3.6V o Spread Spectrum and Active Emissions Limiting o Passes EMI Limit Unfiltered with Up to 24in (61cm) of Speaker Cable o High 94dB PSRR at 217Hz o Click-and-Pop Suppression o Thermal and Overcurrent Protection o Low 0.5µA Current Shutdown Mode o Space-Saving, 2mm x 2mm x 0.8mm, 8-Pin TDFN Package MAX9830 The MAX9830 mono 2W Class D amplifier provides Class AB audio performance with Class D efficiency. Active emissions limiting edge rate and overshoot control circuitry greatly reduces EMI. A patented filterless spread-spectrum modulation scheme eliminates the need for output filtering found in traditional Class D devices. These features reduce application component count. The MAX9830’s industry-leading 1.6mA at 5V, 1.2mA at 3.6V, quiescent current extends battery life in portable applications. The MAX9830 is available in an 8-pin TDFN (2mm x 2mm x 0.8mm) and is specified over the extended -40°C to +85°C temperature range.
