Part Number: REF80 I am using the ref80 in a circuit that is disconnected from the power supply after heat-up and is powered only by supercapacitors. The reference source is wired as shown in the datasheet.
The capacitors are charged to ±15V; as soon…
Part Number: REF80 Tool/software: Hello team,
My customer is wondering if they do multiple reflows, does it affect the accuracy or temp coefficient of REF80?
Customer might reflow their boards for replacing some other parts on the board for regular…
Part Number: REF81 Other Parts Discussed in Thread: REF80 , REF54 Team,
I have a customer who cannot find a reference that meets their needs, after testing many from other vendors. I don't think they have tested our latest, so I am going to recommend…
Hello Arya,
The best option for references with low long-term drift is our newest device: REF80. The output voltage of REF80 settles and stops drifting after around 400-500 hours, as can be seen in the datasheet:
This output voltage settling behavior…
Part Number: INA1620 Other Parts Discussed in Thread: RES11A-Q1 , REF80 , Tool/software: Dear TI Experts,
We have a project to build an input signal conditioner for a high precision ADC. Part of it is to divide the input by half while keeping the INL…
Hi Rachael Parker,
I don't know much about measuring resistor noise, the only method I have ever seen is to measure the intrinsic noise of your system by shorting the inputs, then measure the resistor "output" when it is connected to the inputs (seems…
