OPA2810: Need Input-referred voltage noise data

Gabriel Garza45

Part Number: OPA2810
Other Parts Discussed in Thread: OPA810

Hello, we have a customer looking for the Input-referred voltage noise, which is listed as TBD in the datasheet. Could someone please help track this down?

Also, what is the projected availability of this device, as well as the OPA811?

Thanks,

Hi Gabriel,

The OPA2810 input referred voltage noise seems to be 5.7nV/rtHz for f = 100kHz and above. Is the customer interested in low frequency integrated noise from f = 0.1 to 10Hz which is listed as TBD in the EC table?

Best Regards,
Rohit

Dear Rohit,

Thanks for the quick reply. Ideally, I am interested in the voltage noise corner frequency. Do you have this value or even better the respective frequency plot?

Best regards,
Bjorn

Hi Bjorn,

I am looking into the input referred voltage noise data across frequency and should provide with the data pretty soon.

Best Regards,
Rohit

Hi Rohit,

Thank you very much for the data!

We are interested in the single device package OPA810 or OPA811. When are these devices available for purchase?

Best,

Bjorn
