Is there anybody who can help provide me the parameters of ' Gain Long-Term Drift' or ‘Resistor Matching Ratio Long-Term Drift’' under condition of 70°C and 2000 hours for INA159? thanks in advance!
The gain of the INA159 is set by the ratio of internal SiCr resistors. These resistors have excellent stability and matching characteristics. Though we do not have long-term data specific to the INA159, we have much experience with these resistors on many types of products. I would expect that the gain change at 70'C for 2000 hours to be very small and difficult to measure, probably in the range of 10ppm.
Great! thanks for your reply.
