Hi,
My opamp looks like it isn't amplifying and I need some help. I have a MCP606 opamp in a DIP package.
I am inputting a very fast (almost 1GHz) sine wave into this OPAMP on the + input, but this is a very low voltage signal usually between 10 to 30 millivolts.
Then want to amplify this signal at least 1000-fold, so I connected the output to the - input with a 1000 ohm resistor and further, a 1 ohm resistor connecting this same - input to ground, to get the desired amplification.
But when I connect the Oscope to the output of the OPAMP, it does not show any amplification of the input signal.
In fact, the magniture of the output is still in the 10-30 MV range - the same as the input.
I forgot to mention that I have also connected a 0.01 F cap between GND and Vdd, as recommended.
Can anone tell me why this is not amplifying? Is the signal too fast for this amp?
--thx, jw
