Hello Team,
My customer wanted to know the closed-loop output impedance (at G=+1) of OPA376-Q1. In the datasheet, it states that open-loop output impedance is typically 150 ohms.
Can you also confirm the max input voltage offset of this device is 25uV for all temperature ranges? As I checked the datasheet this is only for 25 degrees Celsius, do we have the data for all temperature ranges?
Thanks in advance.
Regards,
Renan
Hi Renan,
Please check the following thread, which the question has been answered.

Yes, Vos_max is specified 25uV at room temperature. If you are talking about 70C operating temperature, the worst case at Ta = 70C will be 25uV + 1uV/C * (70-25C) =70 uV (if -40C < Ta < 85C).
If you are talking about -40C to 125C in operating range, the worst case (maximum) at Ta = 125C will be Vos = 25uV + 2uV/C*(125-25C) = 127uV.
0.32uV/C is a typical dVos/dT value from the datasheet, if Ta is operating from -40C to +125C.
If you have additional questions, please let us know.
Best,
Raymond
