Original question:
OPA320: A question about the "1 MHz, Single-Supply, Photodiode Amplifier Reference Design"
Tool/software: Code Composer Studio
I am using the launchpad which has a reference photodiode design to do a light detection design. however, I found this reference design is not stable when light added to the photodiode on the launch pad. it will oscillate at 4-500hz. this can be observed at the buffer output before getting into ADC. please help take a look and advice on the fix.
Hi Haibin,
Which one did you mean that "it will oscillate at 4-500hz"? Could you give me a more detailed issue description you'd been stopped?
BTW, the out-of-box demo of the Launchpad is just a demo example for reference. Please find the implementation of the light sensor mode below in the User's Guide of the board
