1. Guaranteed by characterization results.
2. Tested in production at VDD = 3 V ±10 mV.
3. 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.
4. Comparator consumption only. Internal reference voltage not included.
