Product Summary
The LT1491CS is a dual op amp operated on all single and split supplies with a total voltage of 2V to 44V drawing only 40µA of quiescent current per amplifier. The LT1491CS is reverse supply protected; the device draws no current for reverse supply up to 18V. The input range of the LT1491CS 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 LT1491CS is unity-gain stable and drive all capacitive loads up to 10,000pF when optional 0.22μF and 150Ω compensation is used. The applications of the LT1491CS include Battery- or Solar-Powered Systems Portable Instrumentation Sensor Conditioning, Supply Current Sensing, Battery Monitoring, Micropower Active Filter and 4mA to 20mA Transmitters.
