Hello,
I am trying to develop a low power EEG measurement system based on the INA333 ECG example showed in its datasheet. As I am planning to realize the design with the INA2141 I don't know if this is the best option (as there is no model of the INA2141).
I am not 100% of the proper result plot of the 1/Beta graph and I am having troubles to plot the real open loop gain of the OPA333 in order to get the frequency compensation done.
Some pictures are attached to clarify the questions.
Am I missing something or the results are the expected?
Regards,
Alberto
