INA2128: INA2128 output impedance or resistance

Part Number: INA2128
Other Parts Discussed in Thread: INA128

We couldn't find anything in the the  INA2128 data  sheet about output impedance or resistance for this device. Please advise  if we have such spec. Thanks

 

  • Hello Naser,

    It happens that we have measured the closed-loop Zout for the INA128. Below, you can see graphs of its Zout, output impedance and phase vs frequency. The blue curve is for an output current equal to Iq/8, and the red curve is for an output current equal to Iq/2.

    The Zout of the INA128 is applicable to the INA2128 because the latter is the dual version, of the single.
