description:
  The MAX98396 is a mono Class-DG speaker amplifier with I/V sense.
  The device provides a PCM interface for audio data and a standard
  I2C interface for control data communication.
  The MAX98397 is a variant of MAX98396 with wide input supply range.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
