Quiescent current is 250 µA, which is low enough to leave on in a battery-powered design without draining the pack overnight. That is fine for feeding an ADC input or a microcontroller pin, but do not expect to drive a long twisted-pair cable or a meter movement directly. If you need to push a signal more than a few inches on the board, buffer the output.
A close functional peer is the AD8418ABRMZ from Analog Devices, also a single-channel current sense amplifier in a similar package. The AD8418ABRMZ offers a 250 kHz bandwidth and 1 V/µs slew rate, with a wider temperature range of -40°C to 125°C. It is a tube-packaged surface-mount part and can serve as a second-source candidate, though pin compatibility should be verified against your layout.
Yes, the minimum supply span is 2.85 V, so it operates on a 2.85 V rail. The maximum is 36 V, giving you headroom for 24 V or 28 V industrial buses.
