For a basic instrumentation amplifier circuit diagram using AD 620 ic.

[shibas]

Can any body help me by sending a basic instrumentation amplifier circuit diagram using Ad 620 ic.I need a gain of about 100 or below 100.

What's wrong with the datasheet https://www.analog.com/static/imported-files/data_sheets/AD620.pdf ?

the circuit which i connected give me very high gain than that is expected.

the circuit which i connected give me very high gain than that is expected.So what to do?

As I said, use the datahseet.

The equation is G = 1 + (49.4 kΩ/RG) or Rg= 49.4 kΩ / (G-1)
There is also a table in page 15 that gives the gain for several resistance values
