4. Functional Notes

️· ADCMP601 and ADCMP602 Hysteresis: These comparators allow you to adjust hysteresis. This can be useful to prevent oscillation in noisy environments. Bias the LE/HYS pin with a resistor or current source to achieve the desired hysteresis.
️· ADCMP602 Shutdown: The SDN pin can be used to shut down the comparator, reducing power consumption when it’s not actively comparing.

In essence, this datasheet describes three related but distinct comparators, each with slightly different features and packaging options, making them suitable for a range of applications depending on the specific requirements.
