REF35: Looking for negative voltage reference device

Kazuhiko Hirano

Part Number: REF35
Other Parts Discussed in Thread: REF70

Tool/software:

Hello,

My customer is looking for a small size voltage reference device to generate Vo = -1.25V from Vin = 3.3V or -3.3V.
Does TI have any solutions to meet their requirements?

Best regards,

K.Hirano

    Hello Hirano-san,

    Section 9.2.1 of the Typical Applications section of the REF35 datasheet shows how you could do this:

    Depending on the accuracy requirements, REF35125QDBVR (REF35), REF7012QDGKR (REF70), or REF5025IDR (REF5025) would all be great options.

    What is the application for this negative voltage? Would the customer be accepting of a solution such as this? I am happy to make the best part recommendation based off accuracy and other application requirements.

    Thanks,

    Jackson
