Table 63. Comparator 2 Characteristics - STMicroelectronics STM32L151QCH6 Manual

Electrical characteristics
1. Guaranteed by characterization results, 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 not included.
