instrumental amplifier

I am trying to understand the DC return path in an instrumentation amplifier and its effect on the circuit. I would like to know how the behavior changes depending on the source impedance specifically, what happens when the source is high impedance versus when it is a 50Ω source?

Hello, colleagues! There is INA125 powered by plus 24V and -10V, created by ICL7660AIBA. For some reason, the output signal without load is quite noisy, about 100mV, due to which the zero point is shifted. I don’t know what to assume, so I’m asking you for advice and recommendations. The...

Hi, I am hoping I may be able to get some guidance and or ideas in identifying a problem I have with an instrumentation amplifier I have designed. I have simulated the design in Circuit Lab, however I am not getting the expected output as desired during a DC sweep. Essentially, I have a voltage...

So I am planning to use an AD620 instrumentation amplifier in my circuit. The gain formula is G = 1+(49.4KOhm/Rg), Rg being the deciding resistance value. By that logic if a 100K preset or Pot is set to zero, Gain attempted is (∞ + 1), which besides being impossible is also way above the 10000...

Hi, I am working on INA128 instrumental amplifiers for taking the signal from forearm muscle. I am operating on 5v single power supply to power up the INA128. I am dividing these 5v into two voltages with respect to 2.5 reference voltage(5v to 2.5v and 2.5v to 0v). The maximum rail is 5v and...
