I've just assembled a wave shield and it isn't working. I've assembled one of these before without issues so I'm not sure what went wrong.
There was one step during assembly that the instructions were not clear on though, so I'm wondering if I this is the issue.
The instructions for the opamp state:
The photo shows the TS922 which has a notch as well as a circle next to the notch, indicating pin 1.This is a similar-looking chip to the DAC. Again, check that the notch matches the silkscreen notch. In this photo, thats to the left.
Well, my opamp chip doesn't have a notch. My kit came with a TLV2462 which has no notch at all, but does have a circle, which I am assuming indicates pin 1, so I oriented the chip based on that information.
I've attached photos of the front and back. On the photo of the back the photo makes it look like two pads are touching (top, left of center) but they are not.
I'd appreciate some help figuring out what went wrong.
Thanks,
Andy.
