Description

The LT1636 op amp operates on all single and split supplies with a total voltage of 2.7V to 44V drawing less than 50?A of quiescent current. The LT1636 can be shut down, making the output high impedance and reducing the quiescent current to 4?A. The LT1636 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 unity-gain stable into all capacitive loads up to 10,000pF when a 0.22?F and 150? compensation network is used.The LT1636 is reverse supply protected: it draws no current for reverse supply up to 27V. Built-in resistors protect the inputs for faults below the negative supply up to 22V. There is no phase reversal of the output for inputs 5V below VEE or 44V above VEE, independent of VCC.The LT1636 op amp is available in the 8-pin MSOP, PDIP and SO packages. For space limited applications the LT1636 available in a 3mm ? 3mm ? 0.8mm dual fine pitch leadless package (DFN).Applications Battery- or Solar-Powered Systems Portable Instrumentation Sensor Conditioning Supply Current Sensing Battery Monitoring MUX Amplifiers 4mA to 20mA Transmitters
