i used AD8220 in simple with gain=1(no resistor).
i expect Vo swing between +/-5 Volt according to Vo = G • ( VIN(+) – VIN(-) ).
i have large offset at output.
what is wrong in my circuit?
i attached circuit file too.
I am trying to simulate AD8220 in a very simple configuration. G=1 (no resistor connected), single input supply of 5V and REF connected to ground. Is this a legitimate way to use this component? For input levels below 100mV (ie IN+ = 100mV, IN- …
Hello fellow engineers and enthusiasts,
I've been using this instrumentation amplifiers for a few months now, and I absolutely love it for its robustness and pricing. I'm about to do a design that will need to adjust the offset, and the AD8220 offers…
In my previous design, AD8220 was chosen because of the requirement of the extremely high input impedance. However, I need to modify the circuit design by adding a demultiplexer to perform a 1 to 4 switch function and ADG1209 seems suitable for my design…
I am using AD8220 for temperature measurement (using thermocouple). The circuit below is only hot junction measurement, for cold junction reference measurement I use a separate RTD
I was testing the part @ 125 C and observed that it had stopped functioning…
The AD8220 looks very similar. It also has a JFET input stage. It's directly available in LTspiceXVII.
You could check the ff ADI instrumentation amplifiers
By the way, what is your intended application?
i have plan on using ad8220 in the following configuration. is it the best choice for my application ?
