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.
