#123832 - Use a scope to check it Responding to: ???'s previous message |
The AD7862 has a /CS and a /RD line to read the binary result of a conversion. Please take a scope, trigger it with the /RD or /CS line and have a look directly at the outputs of AD7862, while giving 0V to all the analog inputs (by connecting the inputs to analog ground).
Now, you should see a rather stable conversion result of a few LSB, due to unavoidable offset. Result may change by 1LSB. Kai |
