Part Number: REF2030 Other Parts Discussed in Thread: REF1930 , REF3430 Hello,
I am considering REF2030, REF1930, and REF3430 for a new design for +100kHrs operation. While there is datasheet specification of long term stability i.e. 60ppm for the…
Other Parts Discussed in Thread: REF1930REF1930 electric circuit as follows:
when power on, Vbias 1.5V overshoot exceed 10%,the same PCB another REF1930 is normal,why is that?
Dear Joseph,
thank you very much for your support,
can we used REF1930 instead of voltage divider. It has 2 output so we can used 3V supply to our Analog section like opamp & sensors & 1.5Volt we can apply to -ve pin of each analog input channel…
Hi Pete,
Here are my answers:
1) Yes. The oscilloscope is ac coupled.
2) The 1,5Vref(from ref1930) and 3Vref(from ref1930) and 3,3V power supply already been verified. Are OK. Very clean.
3) The capacitors are to decouple and clean the 1,5Vref…
Part Number: ADS131A04 Other Parts Discussed in Thread: REF1930 , ADS127L01 We are utilizing the ADC as a single 3.3V device with an external REFEXT of 3.0V supplied by a REF1930. The analog signals are offset to 1.5V also from the REF1930. We are using…

Ryan, thank you for the advice. I have chosen the TPS79601 LDO to generate a 3V AVDD supply. May I ask how supplies are separated in the ADS127L01EVM? And another question if you have time. The ADS127L01EVM uses the REF6025 to generate a VREF of 2.5V…
