REF3430: long term stability at 50C

Part Number: REF3430
Other Parts Discussed in Thread: REF34

Hi team, 

do you have long term stability of REF3430 at 50C? Customer use case is 45-60C, thanks!

    Hello Rayna,

    The long-term drift will probably be similar to the performance shown in the datasheet. The datasheet long-term stability test holds the devices at 35°C to make sure effects of temperature drift are removed, but the trend will probably be similar at 45°C to 60°C. 

    Thanks,

    Jackson

    Hi Jackson,

    Do you have exact value at 50C? because ADR3430 has 50C data for long term stability, we want to replace it, could you share it to help win? thanks!

    Hello Rayna,

    We do not have data at 50°C. Please use the other performance benefits of REF34 to convince the customer to choose the TI part. Benefits include:

    • REF34 has 2x better initial accuracy
    • REF34 has 25% improvement for temperature drift
    • REF34 has 30% improvement for noise
    • REF34 has lower quiescent current

    Thanks,

    Jackson
