REF1925: Operation at -55C

Part Number: REF1925

Hello,

The REF1925 d/s specifices that the REF19xx series has an operating temp of -40C to 125C. Page 4 says the abs max rating can go down to -55C

Could I use this part for -55C design? If not is there a similar part you'd recommend?

Best,

Adam

    Hi Adam,

    The REF1925 will be functional from -55C to 150C but its performance is not guaranteed. The value of -55C is often used for start-up in applications that will eventually warm up to the operated value.

    Do you need performance at -55C?

    What application is this for? If you want, you can contact me via e-mail and we can discuss this further.

    If you need functionality and performance, try the REF34xx-EP which has guaranteed performance from -55C to 125C.
