OPA2322: input voltage noise in comparison to Q1 (automotive) equivalent

Lenio Cacula

Part Number: OPA2322

The OPAx322 electrical characteristics table in the datasheet shows input voltage noise of 2.8µVpp. The OPAx322-Q1, shows 4.5µVpp. Both datasheets however, show the same chart (Figure 10) for input voltage noise. Can you please comment on that?

Thank you!

Lenio,

I have taken a look at this issue and it seems the 4.5uVpp is correct. This has been reported and will be corrected.

Why is the input noise the only difference between those parts? Noise densities for voltage and current are the same between the two. Why is the automotive different than the non-automotive anyway? The test conditions seem to be the same.

Hey Lenio,

I believe this is a typo on the datasheet.
