Texas Instruments INA205AID

Description
The INA203, INA204, and INA205 are a family of unidirectional current-shunt monitors with voltage output, dual comparators, and voltage reference. They can sense drops across shunts at common-mode voltages from -16V to 80V. The devices are available with three output voltage scales: 20V/V, 50V/V, and 100V/V, with up to 500kHz bandwidth. They also incorporate two open-drain comparators with internal 0.6V 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 1.2V reference output. The INA203, INA204, and INA205 operate from a single 2.7V to 18V supply and are specified over the extended operating temperature range of -40°C to 125°C.
