LT1638IS8#PBF

LT1638IS8#PBF is a low power dual rail-to-rail input and output op-amp. The op-amp operates on all single and split supplies with a total voltage of 2.5V to 44V drawing only 170μA of quiescent current per amplifier. It is reverse battery protected and draw no current for reverse supply up to 18V. The input range includes both supplies, and a unique feature of this device is its capability to operate over the top with either or both of its inputs above V+. The inputs handle 44V, both differential and common mode, independent of supply voltage. The input stage incorporates phase reversal protection to prevent false outputs from occurring when inputs are below the negative supply. Protective resistors are included in the input leads so that current does not become excessive when the inputs are forced below the negative supply. Typical applications include battery- or solar-powered systems, supply current sensing, battery monitoring, micropower active filters and 4mA to 20mA transmitters.
