AD 600 JN

Hi,

 

I am Satyabrata. I am using AD600 JN for a Variable Gain Amplifier. I am getting very peculiar result.

 

I used only A1 amplifier of AD600 just to check its single stage operation.

Pin 1- GROUND

Pin 2- Input

Pin 3- GROUND

Pin 4-GROUND

Pin 16- Control Voltage (0.6 Volt)

Pin 15- GROUND

Pin 14- OUTPUT

Pin 13-+5V

Pin 12- -5V

Whenever i am simulating it, i am getting correct output. But, when i am trying it on bread board, i am getting output sinusoidal signal even if i am not giving any input signal on pin 2. How is it possible? It seems like anything feedback stuff is here.

 

Please help me.

Regards,

Satyabrata
