General Description

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.
