DESCRIPTION
The INA206, INA207, and INA208 are a family of high-side, current-shunt monitors with voltage output, dual comparators, and voltage reference. The INA206, INA207, and INA208 can sense drops across shunts at common-mode voltages from −16V to +80V. The INA206, INA207, and INA208 are available with three output voltage scales: 20V/V, 50V/V, and 100V/V, with up to 500kHz bandwidth.
The INA206, INA207, and INA208 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 on 14-pin versions. 14-pin versions also provide a 1.2V reference output.
The INA206, INA207, and INA208 operate from a single +2.7V to +18V supply. They are specified over the extended operating temperature range of −40°C to +125°C.
