The LT
®1490A is an enhanced version of the popular LT1490
op amp with improved input offset voltage (500
µV max) and
output voltage swing (10mV max from V ). It is recom-
mended for all new designs. The LT1490A operates on all
single and split supplies with a total voltage of 2V to 44V,
drawing only 40
µA of quiescent current per amplifier. It is
reverse supply protected; it draws virtually no current for
reverse supply up to 18V. The input range of the LT1490A
includes both supplies and the output swings to both sup-
plies. Unlike most micropower op amps, the LT1490A can
drive heavy loads; its rail-to-rail output drives 20mA. The
LT1490A is unity-gain stable and drives all capacitive loads
up to 10,000pF when optional 0.22
µF and 150Ω compensa-
tion is used.
The LT1490A 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
15V. There is no phase reversal of the output for inputs 15V
below V or 44V above V , independent of V +.
The LT1490A dual op amp is available in the 8-pin MSOP,
PDIP and SO packages.
