LT1491 - Dual and Quad Micropower Rail-to-Rail Input and Output Op Amps

Download the LT1491 datasheet PDF. This datasheet also covers the LT1 variant, as both devices belong to the same dual and quad micropower rail-to-rail input and output op amps family and are provided as variant models within a single manufacturer datasheet.

General Description

The dual LT ®1490 and quad LT1491 op amps operate on all single and split supplies with a total voltage of 2V to 44V drawing only 40µA of quiescent current per amplifier.

These amplifiers are reverse supply protected; they draw no current for reverse supply up to 18V.

LT1490/LT1491 Dual and Quad Micropower Rail-to-Rail Input and Output Op Amps FEATURES s s s s s s s s s s s s DESCRIPTION The dual LT ®1490 and quad LT1491 op amps operate on all single and split supplies with a total voltage of 2V to 44V drawing only 40µA of quiescent current per amplifier. These amplifiers are reverse supply protected; they draw no current for reverse supply up to 18V. The input range of the LT1490/ LT1491 includes both supplies and the output swings to both supplies. Unlike most micropower op amps, the LT1490/ LT1491 can drive heavy loads; their rail-to-rail outputs drive 20mA. The LT1490/LT1491 are unity-gain stable and drive all capacitive loads up to 10,000pF when optional 0.22µF and 150Ω compensation is used.
