Problem with ADC channels offset #15

Closed Alkohost closed 3 years ago

Alkohost commented 3 years ago

When I connect a I/O board I loose part of the signal (please see the example with test sine) with a presence of a huge offset. What could be the reason for this?

Solved. Problem was in TPS60403DBVR (lack of a negative supply for analog peripherals).
