| 12 | description: |
| 13 | The MAX98388 is a mono Class-D speaker amplifier with I/V feedback. |
| 14 | The device provides a PCM interface for audio data and a standard |
| 15 | I2C interface for control data communication. |

| 47 | For cases where a single combined channel for the I/V feedback data |
| 48 | is not sufficient, the device can also be configured to share |
| 49 | a single data output channel on alternating frames. |
| 50 | In this configuration, the current and voltage data will be frame |
| 51 | interleaved on a single output channel. |
