The INA203-Q1 can sense drops across shunts at common-mode voltages from –16 V to +80 V. The INA203-Q1 is available with 20-V/V gain with up to 500-kHz bandwidth. The INA203-Q1 incorporates two open-drain comparators with internal 0.6-V references and also provides a 1.2-V reference output. The comparator references can be overridden by external inputs. Comparator 1 includes a latching capability, and Comparator 2 has a user-programmable delay. The INA203-Q1 operates from a single 2.7 V to 18 V s...
