OPA320: Input Offset Voltage and Drift

Hi Michael,

Are the input offset parameters that are specified in the datasheet +/-150uV and +/-5uV/V?

Regarding to the input offset voltage, Yes, the max. Vos is +/- 150uV (typical is +/-40uV). The max. input offset voltage in dVos/dT vs. temperature is +5uV/C.

I think that dVos/dT stated as positive is: For a given part, the Vos either increasing with temperature (e.g. positive temperature coefficient) or Vos decreasing with temperature (e.g. negative temperature coefficient). In either cases, dVos/dT will remain positive. 

If you have other questions, please let us know. 

Best,

Raymond
