The SOT-23-5 package is a common, easy-to-source footprint. The supply range and temperature grade cover the majority of industrial and automotive low-side and high-side current-sense applications.
The INA180A2IDBVR is a fixed-gain current-sense amplifier. The 'A2' in the order code indicates a gain of 50 V/V. This is a factory-set gain; no external resistor network is needed.
The output is rail-to-rail, meaning the output voltage can swing from near ground to near the positive supply rail. This is useful when driving an ADC with a single-supply reference.
The INA180A1IDBVR has a gain of 20 V/V, while the INA180A2IDBVR has a gain of 50 V/V. They are pin-compatible in the same SOT-23-5 package, so a board swap is possible if the gain change is acceptable in the system. The supply range, bandwidth, and temperature grade are identical across the INA180 gain-option family.
