The LT
®
1636 op amp operates on all single and split supplies
with a total voltage of 2.7V to 44V drawing less than 50µA of
quiescent current. The LT1636 can be shut down, making the
output high impedance and reducing the quiescent current to
4µA. 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 0.22µF 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
is no phase reversal of the output for inputs 5V below V

The LT1636 op amp is available in the 8-pin MSOP, PDIP and
SO packages. For space limited applications the LT1636 is
available in a 3mm × 3mm × 0.8mm dual fine pitch leadless
package (DFN).
