The MAX98303 stereo 3.1W Class D amplifier provides Class AB audio performance with Class D efficiency. This device offers five selectable gain settings (6dB, 9dB, 12dB, 15dB, and 18dB) set by a single gain-select input (GAIN).
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 IC's 2.0mA at 3.7V, 2.7mA at 5V, quiescent current extends battery life in portable applications.
The IC is available in a 16-bump WLP (1.68mm x 1.68mm x 0.64mm) package specified over the extended -40°C to +85°C temperature range.

Evaluation Kit for the MAX98303
Product Detail
The MAX98303 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX98303 stereo 3.1W Class D amplifier in a 16-bump, 0.4mm pitch wafer-level package (WLP). The EV kit operates from a single 2.6V to 5.5V DC power supply and is capable of delivering 3.1W into a 4Ω load. The EV kit accepts a differential or single-ended audio input and provides differential outputs for the speaker. The device outputs can be connected directly to a speaker load for filterless applications; however, a filter can be added to ease evaluation.
