Dear team.
For AD8420 port surge protection, what is the appropriate protection voltage for TVS?

Dear team,
I used LTSpice to simulate the 4-20mA receiver of CN-0314, and the simulation results were wrong. Don't know the reason.
Please point out the error, thank you.
Hi. I have a problem with a design that I made with the AD8420. I proceed to place the schematic diagram to explain more clearly my problem.
Design a transmitter that receives a voltage of 0 to 10V at its input. The output must obtain a current in the…
如题:AD8420在使用3.3V单电源供电时,放大倍数不对!而使用5V单电源供电时正常。
我是按照PDF手册推荐电路做板测试的
使用3.3V单电源工作,放大倍数是201倍时(1K和200K组合),
输入3.3mV,输出电压只有0.460V,和0.663V相差太远了
我把后续电路割断了,也是这样
而把单电源换成5V,放大倍数正常
请问这种情况正常吗?
Hi guys,
I am using AD8420 in 4-20mA current loop receiver configuration. Referring document is https://www.analog.com/media/en/reference-design-documentation/reference-designs/CN0314.pdf
I am using 3.3V external reference instead of ADR02 for voltage…
I have a simple AD8420 configured as a 4-20mA receiver powered by +12v/GND . The issue I have is that the output is only valid if I tie the return of the 4-20mA source (AI420_4_N) to the same ground as my board (DGND).
I'm within the common mode requirements…
It has AD8420.cir but not sure how to install this into LTSpice.
When you going to release LTSpice version of AD8420.
Thanks.
Hello everyone, I have a problem with the AD8420 in-amp in a new electromagnetic flow meter design. Please refer to the attached image of a section of the circuit diagram.
The AD8420 is powered from a 3 V supply with the REF pin connected to mid-rail…
