Table 64. Comparator 2 Characteristics - STMicroelectronics STM32L151CCT6 Manual

STM32L151xC STM32L152xC
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.
