Hi,
I am trying to get to the bottom of a rather stubborn circuit instability and want to rule out a few things. I am driving two instrumentation amplifiers (INA111's) - either both + inputs or both - inputs, never mixed - from a common source. The source is basically a passive low-pass filter. I figured that since the input impedance (of the instrumentation amplifiers) is very high then there should be no problems doing this. Am I right?
Thanks!
