Tool/software:
Hi,
I am testing the AMP-PDK-EVM, with the SOIC-8 daughter board, I have a OPA827AID. When I test the voltage buffer, I am able to replicate the signal. But the 101x or the 1001x gain doesn't seem to work as needed. I have a dual channel power supply, in which I am shorting the two terminals (+ of one and - of the another), creating my V+, V- and Gnd. I checked if this is fine, with a multimeter and all good. Giving a 12Vpp power. Rest apart, if should be just a simple connection, where I provide a 1KHz, 200mVpp Sine wave as an input, expecting a 20Vpp in the 100x gain. Attaching some images of the connection. Not sure where I am making a mistake.
I just get noise in the output. Any help would be better.
Regards
Ram.
