Product Overview

The LT1491ACDHC#PBF is a quad Operational Amplifier with a low input offset voltage of 500µV maximum. The LT1491A operate on all single and split supplies with a total voltage of 2 to 44V, drawing only 40µA of quiescent current per amplifier. The amplifier is reverse supply protected, they draw virtually no current for reverse supply up to 18V. The input range of the LT1491A includes both supplies and the output swings to both supplies. Unlike most micropower op amps, the LT1491A can drive heavy loads, their rail-to-rail outputs drive 20mA. The LT1491A is unity-gain stable and drive all capacitive loads up to 10,000pF when optional 0.22µF and 150R compensation is used. The LT1491A has an 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.
