Product Summary
The LT1490CS8#TRPBF is an Op Amps. The LT1490CS8#TRPBF operates on all single and split supplies with a total voltage of 2V to 44V drawing only 40mA of quiescent current per amplifier. The LT1490CS8#TRPBF is reverse supply protected; they draw no current for reverse supply up to 18V. The input range of the LT1490CS8#TRPBF includes both supplies and the output swings to both supplies. Unlike most micropower op amps, the LT1490CS8#TRPBF can drive heavy loads; their rail-to-rail outputs drive 20mA. The LT1490CS8#TRPBF is unity-gain stable and drive all capacitive loads up to 10,000pF when optional 0.22mF and 150W compensation is used. The applications of the LT1490CS8#TRPBF include Supply Current Sensing, Battery Monitoring, Micropower Active Filters and 4mA to 20mA Transmitters.
