Hi Tom,
Thank you for your help.
an external votage reference delayed it's a good idea, unfortunately the ads8028 will be placed on a my daugther board and no more control signals are available to manage the delayed external voltage reference.
In REF5040…
Thanks.
More questions:
1. Is the 1k Ohm resistor at VREF5030's VOUT pin necessary?
2. Why are two separate RC loads required at the Reference output if only one unity gain op-amp is shared between VREFHIA and VREFHIB?
3. The REF5040 datasheet doesn…
Part Number: ADS8686S Other Parts Discussed in Thread: REF5040 Hello,
On ADS8686S 16 CH ADC
I want to use external Voltage reference on REFIO pin. I want use REF5040 IC which has 4.096V Vout. Is it possible to use Vref 4.096V and DVDD 3.3V ? I am using…
Part Number: REF5040 Other Parts Discussed in Thread: TMUX6121 I am using the REF5040 in a new design. The version in the VSSOP 8-pin package has a pin pitch of 0.65mm according to the datasheet.
In the same new design, I am also using the TMUX6121. The…

hi Abhijeet Godbole
a REF5040 has been used in my design to provide a voltage reference,
here is a confusing situation, the Vin of REF5040 is 5.0V, the Vo of REF5040 is 5.0V(should be 4.096V, however, 5.0V with or without load circuits), but…
Part Number: REF5040 Other Parts Discussed in Thread: REF3140 This customer has failed EMC testing and identified the REF5040 as being the culprit. Once the device is replaced with REF3140, the board passes the test. Can you please provide any insight…
Part Number: REF5040 Hi there,
We are currently using this IC as a reference voltage for a ADC.
The problem is that while passing the circuit through RF radiated immunity tests the output pin is not stable and we are getting erroneous ADC readings.
