Amplifying dc signal using AD524

  • #1
Hi all;

I am trying to amplify a dc signal using the AD524 amplifier .
I connected the input- pin (pin 1) to the ground. pin 2(input+) to 0.5V (The 0.5 came from a varibale resistor).
pin 3 (RG2) was connected to G=10 (pin 13). Ref.(pin 6) was connected to ground. Pin 7 (VS+) 9V.
pin 8 (VS-) to -9V.Pin 10 (sense) was connected to pin 9 (o/p).
Pins 4,5,11,12,14,15,16 were not connected. The output is always -4.5V.
I disconnected the RG2 from the G=10 and connected it to G=100 the o/p remained -4.95V.
I disconnected RG2 but the o/p is still -4.95V. I varied the input Voltage the o/p still th same.

I dont know were is the problem. Is it correct to keep pins 4,5,14,15,16 unconnected?
IS it correct to connect the ref pin to the ground? What do you think is the problem?

I would be very grateful if anyone can help me with it.

Regards Mostafa
