DESCRIPTIO
The LT
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 250µA of quiescent current. The LT1637
can be shut down, making the output high impedance and
reducing the quiescent current to only 3µA. The LT1637 is
reverse supply protected: it draws virtually no current for re-
verse supply up to 25V. The input range of the LT1637 in-
cludes 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. The LT1637
is unity-gain stable into all capacitive loads up to 4700pF
when optional 0.22µF and 150Ω compensation is used.
The LT1637 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 V
The LT1637 op amp is available in the 8-pin MSOP, PDIP
and SO packages. For space limited applications, the
LT1637 is available in a 3mm × 3mm × 0.8mm dual fine
pitch leadless package (DFN).
