LT1491ACS#PBF - Linear Technology Function Overview

The LT1491ACS#PBF is a quad over-the-top micropower rail-to-rail input and output Operational Amplifier with a low input offset voltage of 500µV max. The LT1491A operates on all single and split supplies with a total voltage of 2 to 44V, drawing only 40µA of quiescent current per amplifier. This amplifier is reverse supply protected and draws virtually no current for reverse supply up to 18V. The input range includes both supplies and the output swings to both supplies. Unlike most micropower op amp, the LT1491A can drive heavy loads, its rail-to-rail outputs drive 20mA. It is unity-gain stable and drive all capacitive loads up to 10000pF when optional 0.22µF and 150R compensation is used. This op amp has an unique input stage that operates and remains high impedance when above the positive 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+.
