Hi..This is Anirban..I am trying to design an bridge amplification circuit using AD8221 in orcad capture. But while running I am getting an error msg as "ERROR --Subcircuit AD8221 used by X_U10 is undefined"...I am not understanding how to rectify this error..I have given the specifications to AD8221 as follows:

1.Gain selected as 900

2. Vs+ = 5V (same source is given to the bridge ext point)

3. Vs- = gnd

4. REF = gnd

6. Rg= 49.9ohms

I am using Orcad 9.2.

If some one can help me then i would be really thankful...
