LT1783HS5#TRMPBF

LT®1783 is a 1.25MHz, Over-The-Top® micropower, rail-to-rail input and output op-amp. The amplifier draws less than 300μA of quiescent current and has reverse-battery protection, drawing negligible current for reverse supply voltages up to 18V. The input range of this includes ground, and a unique feature of this device is its Over-The-Top®® operation capability with either or both of its inputs above the positive rail. The inputs handle 18V both differential and common mode, independent of supply voltage. The input stage incorporates phase reversal protection to prevent false outputs from occurring even when the inputs are 9V below the negative supply. A shutdown feature on the 6-lead version can disable the part, making the output high impedance and reducing quiescent current to 5μA. Typical applications are portable instrumentation, battery- or solar-powered systems, sensor conditioning, supply current sensing, battery monitoring, MUX amplifiers, 4mA to 20mA transmitters.
