Audio Amplifiers Procurement Notes

Verify the specific suffix 'C' indicates the variant with 13ms volume ramping during turn-on and turn-off. Confirm the 'EWC' package code corresponds to the 12-bump WLP format. Ensure compatibility with the required 1.71V to 5.5V VDD logic levels and 3V to 14V PVDD supply range before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when high output power is required in a compact form factor without external output filters. The C-suffix is appropriate for applications requiring controlled volume ramping to minimize audible transients. Verify that the host processor can provide the necessary BCLK and LRCLK signals within the specified jitter tolerances for reliable operation.

Audio Amplifiers Part Context

This part belongs to the MAX98365 family of tiny, cost-effective, 14V plug-and-play digital Class-D amplifiers. The family offers various gain settings and turn-on characteristics across different suffixes, all utilizing the same space-saving 12-bump WLP package designed for easy integration without expensive in-pad vias.

Audio Amplifiers FAQ

What distinguishes the MAX98365C variant from other models in the series?

The MAX98365C variant features a 13ms volume ramp-up and ramp-down time during turn-on and turn-off, whereas the A and B variants have a faster 1ms turn-on time.

Does the MAX98365 require an external master clock (MCLK)?

No, the device eliminates the need for an external MCLK signal, which reduces EMI and simplifies the system architecture by relying solely on BCLK and LRCLK.
