The MAX98363 is a tiny, low-cost, SoundWire® input Class D mono amplifier that provides industry-leading, Class AB audio performance with Class D efficiency. The device features an internal tone generator, interrupt control, and selectable slew-time settings for SoundWire data output PHY. A novel pinout allows customers to use the cost-effective wafer-level package (WLP) with no need for expensive in-pad vias.
The MAX98363 is a SoundWire peripheral device that supports MIPI SoundWire v1.2-compatible digital interface for audio and control data. The digital interface is highly flexible and supports a variety of input clock frequencies. Also, selectable slew-time controls on the SoundWire data output PHY help minimize EMI on a range of capacitive bus loads. The digital interface operates on 1.8V nominal voltage supply which can be either supplied externally, or generated by an internal LDO.
An internal tone generator, with a variety of frequency options, supports in-factory testing or system boot-up sounds during system power-up. An externally configurable address pin allows up to five unique SoundWire addresses for each device part number. The MAX98363A/B operate with DVDDIO supplied with internal LDO and can support up to 10 MAX98363 SoundWire peripheral devices on one data lane. The MAX98363C/D operate with externally supplied DVDDIO and support up to 10 MAX98363 SoundWire peripheral devices on one data lane.
Active emissions-limiting, edge-rate limiting, and overshoot control circuitry greatly reduce EMI. A filterless spread-spectrum modulation scheme eliminates the need for output filtering found in traditional Class D devices and reduces the component count of the solution.
The device is specified over the -40°C to +85°C temperature range.

MAX98363 DEV Board
MAX98363 Development Board
Product Detail
The MAX98363 Development board (DEV board) is a fully assembled and tested application board that evaluates the MAX98363A/MAX98363B/MAX98363C/MAX98363D, tiny SoundWire® v1.2 compatible input Class-D mono amplifiers.
The MAX98363 Development board is designed to work with an external SoundWire manager, which would provide the v1.2 SoundWire Clock and Data. Only a single supply input of 2.5V to 5.5V for VDD is required for powering the DEV board. Figure 1 and Figure 2 in the data sheet detail the DEV board connections and jumper locations.
