Description

The LT®1490A/LT1491A are enhanced versions of the popular LT1490/LT1491 dual and quad op amps with improved
input offset voltage (500 V max) and output voltage swing (10mV max from V). They are recommended as replacements for the LT1490/LT1491 in all new designs. They operate on all single and split supplies with a total voltage of 2V to 44V, drawing only 40 A of quiescent current per amplifier. These amplifiers are reverse
supply protected; they draw virtually no current for reverse supply up to 18V. The input range of the LT1490A/LT1491A includes both supplies and the output swings to both supplies. Unlike most micropower op amps, the LT1490A/ LT1491A can drive heavy loads; their rail-to-rail outputs drive 20mA. They are unity-gain stable and drive all capacitive loads up to 10,000pF when optional 0.22 F and 150 compensation is used.

The LT1490A/LT1491A have 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. The quad LT1491A is available in the 14-pin SO and PDIP packages.
