I am trying to use a pair of INA116 instrumentation amplifiers for a complex impedance measuring system at up to 25 kHz. I need to determine the phase accuracy of the 2 amplifiers relative to each other at unity gain but the spec sheet only lists a typical gain bandwidth.
Is there a specification for the minimum unity gain bandwidth (lot to lot variation) so I can calculate the potential worst case phase mismatch at various frequencies (particularly the upper frequency requirement)? I realize that greater than the specified typical gain bandwidth only make things better.
Thanks
Don
