The MCP6031 is a high precision operational amplifier (op amp) that features a low typical operating current of 900 nA, a gain bandwidth of 10 kHz, and an offset voltage that is less than 150 µV. The ...

The ADHV4710 op amp operates on dual supplies from ±12 to ±55 V, delivering output current of ±100 mA at the higher voltages. A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF (1000 pF).

Using a resistor and voltage amplifier across it for current sensing presents a conundrum. On one hand, it appears to be near-trivial application of Ohm’s Law via I = V/R. It certainly looks easy: A ...
