APPLICATIU
The LT
1636 op amp operates on all single and split supplies
with a total voltage of 2.7V to 44V drawing less than 50
μ
A of
quiescent current. The LT1636 can be shut down, making the
output high impedance and reducing the quiescent current to
4
μ
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
μ
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 V
EE
or
44V above V
EE
, independent of V
CC
.
The LT1636 op amp is available in the 8-pin MSOP, PDIP and
SO packages.
