AD8222
Production
The AD8222 is a dual-channel, high performance instrumentation
amplifier that requires only one external resistor per amplifier
to set gains of 1 to 10...

Dear Sir,
AD8222 LTSpice model include parameters: Gain Vos, IBias, Voltage and current with 1/f noise.
How can I simulate Vos, IBias, and noise spec with LTSpice, and compare them with the datasheet?
I can understand how to measure and simulate these parameter of the general operational amplifier.
Thanks a lot!
Best regards,

Hi DongGuo ,
Good day. This would take multiple test circuit. We'll get back to you.

Hi DongGuo ,
Good day. For the Vos and Ios specifications, the inputs to the AD8222 should be grounded. You can perform a .op run to measure the output voltage (which will correspond to the Vos) and the current at the inputs (which will correspond to the Ibias).

As for the noise specs, you can configure the input as a differential with a noise source using a voltage source. 
Thank you.
