I am using LTC2484 ADC for self diagnosis purpose.
On our custom board we have AD5420 and AD5421 DAC.
We need LTC2484 to monitor the currents from these DAC's.
Can I know whether I can connect like as shown in the attached figure.
LTC2484 datasheet figures 15 through 18 suggest large CREF decoupling capacitors cause gain error. I am puzzled by this. I would expect the opposite. The second paragraph on page 28 is confusing. The first sentence almost seems to suggest that the external…
here is my circuit and adc output.
I expected LTC2484 easy drive cancel the input current which caused offset and noise.
what is the cause of this offset and noise?
how to utilize easy driver to cancel the offset and noise?
when I changed R20,R21…
Considering the maximum supply current drawn from the DVDD of AD5421.
These would already be equal to 5.15mA. We haven't even added the current drawn from the pull-up…
