7.3.3 Comparator

The INA203, INA204, and INA205 devices incorporate two open-drain comparators. These comparators typically have 2 mV of offset and a 1.3-μs (typical) response time. The output of Comparator 1 latches and is reset through the CMP1 RESET pin, as shown in Figure 7-5. This configuration applies to both the 10- and 14-pin versions. Figure 7-4 illustrates the comparator delay.

The 14-pin versions of the INA203, INA204, and INA205 devices include additional features for comparator functions. The comparator reference voltage of both Comparator 1 and Comparator 2 can be overridden by external inputs for increased design flexibility. Comparator 2 has a programmable delay.
