Anyone have a recommendation for a benchtop current sense amplifier?
Sure, there are current sense breakout boards and whatnot. But what I’d like is a convenient device that I can use to instrument a circuit and then monitor its current with my oscilloscope or logic analyzer (Saleae with analog input) along with other signals in the circuit.
Ideal features might be:
- Banana jack inputs and outputs
- Selectable range / sensitivity / sense resistor
- Isolated measurement, so I can measure high-side or low-side currents without worrying too much about the common connection on my scope
- Selectable or automatic power source selection, between circuit-powered and externally-powered
I haven’t seen anything like this in a few targeted searches, and just wondering if someone has any suggestions I might have missed.
