(2) Specified by design; not production tested. (3) See the Comparator Maximum Input Voltage Range section in the Applications Information. (4) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4V. (5) The CMP1 RESET input has an internal 2M Ω (typical) pull-down. Leaving the CMP1 RESET open results in a LOW state, with transparent comparator operation. (6) The Comparator 2 delay applies to both rising and falling edges of the comparator output. Figure 1. Comparator Hysteresis 4 Submit Documentation Feedback |
