• AD8220

    Hi,

    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.

  • AD8220 configuration

    Hi,

    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- …

  • AD8220 Vref

    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…

  • Input impedance of AD8220 with ADG1209

    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…

  • Temperature(thermocouple) measurement using AD8220

    Hi, 

    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…

    Hello Florian,

    The AD8220 looks very similar. It also has a JFET input stage. It's directly available in LTspiceXVII.

    Hi,

    You could check the ff ADI instrumentation amplifiers

    AD8220

    AD8224

    AD8236

    By the way, what is your intended application?
