To sense animals moving I wanted to create a simple IR sensor that would trigger a monostable to generate a rather long pulse when an animal passed by. Further, while the animal remained in front of ...

When it comes to our analog designs, op-amps tend to be just another jellybean part. We tend to spec whatever does the job, and don’t give much of a thought as to the internals. And while it doesn’t ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A outputs, with a digital control bus for setting internal parameters. Called ADHV4710, the output can swing ±52V with ...

After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in preparation for SPICE simulation. The availability of hierarchical blocks for ...

Using the circuits below you can study op amps and characterize their behavior. Comparator Inverting Amplifier The comparator demonstrates the ``open-loop'' behavior of an op amp. You can design the ...
