Tool/software:

I would like to know whether the shunt could work under 125℃.

Does the TCR keep the same?

Thanks!

Hello,

Devices with the extended temperature range will work under 125C and the specifications for the particular orderable part number (OPN) can be found in the EC table of the datasheet.

Best Regards,

Hello

I would like to know whether you could provide a 3V reference offer, shunt voltage, 3V, 0.1%, -40~125℃

Thanks in advance!

Hello,

Unfortunately, we do not offer 0.1% accuracy (A grade) devices in the extended temperature range for this device.

You could consider using the REF30E series voltage reference which offers a 3V option at 0.1% accuracy and over the extended temp. range.

I hope this helps!
