LT1490IS8#PBF | Linear Technology
Dual dual rail-to-rail operational amplifier, SOIC-8, LT1490IS8#PBF
Dual Rail-to-Rail Operational Amplifier, LT1490IS8#PBF, Linear Technology
The LT1490IS8#PBF dual op amp operates on all single and split supplies with a total voltage of 2V to 44V, drawing only 40µA of quiescent current per amplifier. This amplifier is reverse-supply protected; it draws no current for reverse supply up to 18V. The input range of the LT1490IS8#PBF/LT1491 includes both supplies, and the output swings to both supplies. Unlike most micropower op amps, the LT1490IS8#PBF can drive a heavy load; its rail-to-rail output drives 20mA. The LT1490IS8#PBF is unity-gain stable and drives any capacitive load up to 10,000pF when optional 0.22µF and 150Ω compensation is used. The LT1490IS8#PBF has a unique input stage that operates and remains high impedance when above the positive supply. The input tolerates 44V, both differential and common mode, even when operating on a 3V supply. Built-in resistors protect the input from faults below the negative supply up to 22V.
