Parminder,

The INA116 is the only low IB devices that incorporates guard drive into the device. The INA121 and INA819 both have a similar function and low bias current but do not have a guard function. To get the best bias current response with guarding you may want to consider using ultra-low bias current op amp buffer (OPA928 is a good modern low IB buffer). If the IB requirement is not so stringent NA121 and INA819 may work directly.

Best regards, Art

Hello Art Kay

I have some doubt regarding my input voltage supply to the input pins.

We are using a stepped-up DC at the input.

Can we have a meeting so that I can discuss issue with you?

Please suggest me any time when you are free. we can generate a meeting link.
