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.APPLICATIONSNotebook ComputersTabletsIoT DevicesGaming Devices (Audio and Haptics)Smart SpeakersSmartphonesSingle Li-ion Cell/5V Devices
