(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) This voltage may exceed the ratings shown if the current at that pin is limited to 5mA.
DescriptionThe 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 to +125.
