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.

Product Detail

The MAX9830A evaluation kit (EV kit) is a fully assembled and tested circuit board that uses the MAX9830A filterless Class D amplifier to drive a mono bridge-tied-load (BTL) speaker in portable audio applications. Designed to operate from a 2.6V to 5.5V DC power supply, the EV kit is capable of delivering 2W into a 4Ω load. The EV kit accepts differential or single-ended input signals. The MAX9830A EV kit also evaluates the MAX9830B–MAX9830E.
