PRODUCTION DATA
The INA28x-Q1 can make accurate measurements well outside of its own power-supply voltage, V+, because its inputs (+IN and –IN) may operate anywhere from –14 V to 80 V independent of V+. For example, the V+ power supply can be 5 V while the common-mode voltage being monitored by the shunt may be as high as 80 V. Of course, the output voltage range of the INA28x-Q1 is constrained by the supply voltage that powers it on V+. When the power to the INA28x-Q1 is off (that is, no voltage is supplied to the V+ pin), the input pins (+IN and –IN) are high impedance with respect to ground and typically leak less than ±1 μA over the full common-mode range of –14 V to 80 V.
