MAX9830 is a mono 2W D-class amplifier from MAXIM, which provides AB-class audio performance and D-class efficiency. It uses active edge rate and overshoot control circuitry to greatly reduce EMI. The filterless spread-spectrum modulation scheme eliminates the need for output filtering found in traditional D-class devices. These features reduce application component count. MAX9830's industry-leading 1.6mA at 5V, 1.2mA at 3.6V, quiescent current extends battery life in portable applications. 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.
The MAX9830 is a mono 2 W Class D audio amplifier that delivers Class AB performance with Class D efficiency. It features industry‑leading low quiescent current, spread‑spectrum modulation, click‑and‑pop suppression, and built‑in thermal and over‑current protection. The device is offered in an 8‑pin TDFN package (2 mm × 2 mm × 0.8 mm) and operates over a temperature range of –40 °C to +85 °C.
The datasheet includes absolute maximum ratings, detailed electrical characteristics, typical operating curves, pin functions, layout recommendations, and optional component selections such as ferrite bead filters. Application notes cover notebook and netbook computers, cellular phones, and portable audio players.
