Description

The LT 1637 is a rugged op amp that operates on all single and split supplies with a total voltage of 2.7V to 44V. The LT1637 has a gain-bandwidth product of 1.1MHz while drawing less than 250mA of quiescent current. The device can be shut down, making the output high impedance and reducing the quiescent current to only 3mA.

The LT1637 is reverse supply protected: it draws virtually no current for reverse supply up to 25V. The input range of the LT1637 includes both supplies and the output swings to both supplies. Unlike most micropower op amps, the LT1637 can drive heavy loads; its rail-to-rail output drives 25mA. 

It is unity-gain stable into all capacitive loads up to 4700pF when optional 0.22mF and 150W compensation is used. The device 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. 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. Its op amp is available in the 8-pin MSOP, PDIP and SO packages.
