MAX98361CEWL+T

Audio Amplifiers Overview

The MAX98361CEWL+T is a digital pulse-code modulation input Class-D amplifier from Analog Devices. It operates on a single supply voltage ranging from 2.5V to 5.5V and delivers 3.2W of output power into a 4Ω load at 5V. The device features a quiescent current of 2.2mA and standby current of 1.5μA. It supports sample rates from 8kHz to 96kHz with data word lengths of 16-bit, 24-bit, or 32-bit in I2S and left-justified modes. The unit provides 110dB dynamic range and 10μVRMS output noise. It utilizes a 9-pin WLP package measuring 1.26mm by 1.26mm.

Audio Amplifiers Procurement Notes

Verify the specific suffix 'C' indicates the variant with 13ms volume ramping during turn-on and turn-off operations. Confirm the '+T' designation corresponds to the reel packaging format. Ensure compatibility with the required logic levels and verify that the 9-pin WLP footprint matches the target PCB land pattern specifications.

Audio Amplifiers Selection Notes

Select this model when a slow volume ramp is required during power transitions to minimize audible artifacts. The C variant differs from the A and B versions which feature faster 1ms turn-on times. Verify that the application requires the specific gain settings associated with the GAIN_SLOT pin configuration for the desired audio output level.
