LT1636CS8#TRPBF

LT1636 is an over-the-top micropower rail-to-rail input and output op-amp. It operates on all single and split supplies with a total voltage of 2.7V to 44V drawing less than 50µA of quiescent current. The LT1636 can be shut down, making the output high impedance and reducing the quiescent current to 4µA. It has a unique input stage that operates and remains high impedance when above the positive supply. The inputs take 44V both differential and common mode, even when operating on a 3V supply. The output swings to both supplies. Unlike most micropower op-amps, the LT1636 can drive heavy loads; its rail-to-rail output drives 18mA. The LT1636 is reverse supply protected: it draws no current for reverse supply up to 27V. Application includes battery- or solar-powered systems, portable instrumentation, sensor conditioning, supply current sensing, battery monitoring, MUX amplifiers, 4mA to 20mA transmitters.
