hello,

I have a problem in using ADA4870

It's a G=+2 non-inverting amplifier based on an ADA4870

Supply and input conditions are set as:

Vcc,Vee = +-12V

Vin = 30 MHz sinusoidal wave, 0.4Vp-p, Offset = 0, signal generator resistor = 50 ohm

the problem is that the output signal maintained zero after switching on the power supply,

and the output current from power supply was approximately 5mA.

(All the components were set on solderless board)

Could someone  help me to find the solution to this issue?

Thanks a lot.
