Other Parts Discussed in Thread: TLV272, , TINA-TI, INA128
I have a circuit which has a non-inverting amplifier followed by an instrumentation amplifier. NI amplifier is implemented with OPA2180 and instrumentation amplifier is INA128. I simulated this circuit in TINA-TI. I am getting convergence issue. However, when I replace OPA2180 with TLV272, simulation works perfectly. convergence issue occurs only when I use OPA2180. error details indicates the issue with INA128 which is confusing. Wanted to check how I can make it work.
