1. Based on characterization, not tested in production.

2. The delay is characterized for 100 mV input step with 10 mV overdrive on the inverting input, the non-

inverting input set to the reference.

3. Comparator consumption only. Internal reference voltage (necessary for comparator operation) is not

included.
