Connect R15 in series with the op-amp input and then put th e cap from th e op-amp input to ground - this is a filter. There is no need in this type of circuit to focus too heavily on keeping the op-amp input resistances th e same since these source resistances are low enough no to cause any significant errors.

Web6 de mai. de 2024 · Hello, I have a 50A 75mV shunt and I'm trying to measure current using arduino. Here's the schematic of what I currently have on the breadboard: U1 = TL071. R1 = 270. R2 = 47k. So this gives a gain of 174. Everything seems almost OK but even though there is no load, the opamp output is not 3.3v but ~3.47v. Web24 de jun. de 2024 · Shunt (current sense) Resistor Selection. To measure uAs, your current shunt should have a resistance value roughly in the 100s of Ohms or greater. You don’t want to have a very low resistance shunt (say 5 Ohms), with a very large Op Amp Gain, because the shunt will produce very little voltage (5Ohms *150uA = only 750uV).
