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
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 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.

The
q
denotes specifications that apply over the full specified temperature
range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 3: The LT1636C is guaranteed to meet specified performance from
0
C to 70
C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at 40
C and 85
C. The
LT1636I is guaranteed to meet the extended temperature limits.
