MAX9830
Mono 2W Class D Amplifier
2.3W of Low-EMI, Class D Power from a 2.5mm x 2.5mm Package
|
Status
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 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.
