LT1782IS5#TRMPBF

The LT1782IS5#TRMPBF is an Operational Amplifier for use with 4 to 20mA transmitters. The amplifier draws less than 55µA of quiescent current and has reverse battery protection, drawing negligible current for reverse supply voltages up to 18V. The input range of the LT1782 includes ground and 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. The LT1782 can drive loads up to 18mA and still maintain rail-to-rail capability. A shutdown feature on the 6-lead version can disable the part, making the output high impedance and reducing quiescent current to 5µA.
