|
|
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.

For cases where a single combined channel for the I/V sense data
|
|
is not sufficient, the device can also be configured to share
|
|
a single data output channel on alternating frames.
|
|
In this configuration, the current and voltage data will be frame
|
|
interleaved on a single output channel.
