WebJan 10, 2002 · The TLC2272 op amp has rail-to-rail output, yielding a wide output-voltage range, and low quiescent current, simplifying the capacitor-based power supply. Because the TLC2272 is a dual device, you can connect the unused half as a voltage follower. When you monitor a three-phase power line, you'd use one and one-half TLC2272s. WebMay 16, 2016 · The optocoupler will pull the output to ground. You'll want to be careful in general how much current you expect the opto to sink/source, zero-level will start creeping up quickly. Hence the tradeoff with speed, stronger the pull-up and faster it'll go up but then your zero level can easily creep too high. May 16, 2016 at 14:30 Add a comment 0
