8.3.4.8 Sample Rate Calculation
The MAX32600 ADC supports two primary measurement modes for the ADC: Low Power Measurement Mode and High Speed Measurement Mode. Low Power
Measurement Mode uses significantly less power than High Speed Measurement Mode by putting the ADC and PGA, if enabled, in a sleep state between samples.
