Is there any way to control offset and gain error on AD5420 by external circuit like as AD420 (refer to page 10, on AD420 Data sheet)?
Thank you for your help in advance.
Hello! I have a problem with ad420 voltage output. I need VOUT=0-10V.
In my scheme i have 4 independent AD420.From 0 to 3 volts on the AD420 (6 volts after the amplifier) everything works stably. Increasing the voltage, the output signal starts to somehow…
om my board There is one ad7799 and ad420 .
after setup ad7799 I realized that unlike ad7799 the ad420 need clock
to be low in ideal state .
is there any solution for this problem ?
and as i see in ad420 it accept all data in Data in…
Does ADI have the companion chip to the AD420 4-20mA DAC that converts 4-20 into a digital value?
Thank You for the information provided and your efforts. At this time we will be using the AD420 for this particular project.
The AD5422 doesn’t have trim pins like the AD420 so it cannot be trimmed like the AD420. If further trimming is required, it needs to be done in the firmware. On power up the part runs an internal calibration routine, so the user doesn’t need…
Can you define what you mean by "proper output"?
Is the AD420 giving the expected output to the positive terminal?
