MAX98300單聲道2W D類放大器應用電路圖

TheMAX98300mono 2.6W 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 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 MAX98300 industry-leading 0.78mA at 3.7V, 1.1mA 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 -40°C to +85°C temperature range.
