MAX9830 单声道2W D类放大器

MAX9830 单声道2W D类放大器   概述 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 +85deg:C temperature range.   关键特性
