The INA203, INA204, and INA205 are a family of unidirectional current-shunt monitors with voltage output, dual comparators, and voltage reference. The INA203, INA204, and INA205 can sense drops across shunts at common-mode voltages from 16 V to 80 V. The INA203, INA204, and INA205 are available with three output voltage scales: 20 V/V, 50 V/V, and 100 V/V, with up to 500-kHz bandwidth.
The INA203, INA204, and INA205 also incorporate two open-drain comparators with internal 0.6-V references. On 14-pin versions, the comparator references can be overridden by external inputs. Comparator 1 includes a latching capability, and Comparator 2 has a user-programmable delay. 14-pin versions also provide a 1.2-V reference output.
The INA203, INA204, and INA205 operate from a single 2.7-V to 18-V supply. They are specified over the extended operating temperature range of 40°C to 125°C.
