The LT

with a total voltage of 2.7V to 44V drawing less than 50

µA of

quiescent current. The LT1636 can be shut down, making the

output high impedance and reducing the quiescent current to

4

µA. The LT1636 has a unique input stage that operates and

remainshighimpedancewhenabovethepositivesupply.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

µF and 150Ω 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

The LT1636 op amp is available in the 8-pin MSOP, PDIP and

SO packages.
