Analog Discovery 2

[Leo_W]

Hi，digilent

My AD2 signal generator is abnormal, the output waveform is wrong, and the output as a voltage source is also too small. It should be a fault somewhere. Through comparison and measurement, I found that the voltage of the device is abnormal, but it cannot be repaired without the circuit diagram. Do you have the circuit diagram of AD2, or maybe there is something wrong with this board?

As shown in the figure, the voltage of the device in the frame column part is abnormal, and there are other devices that I have not measured yet.Or can you tell me where the board might be going wrong?

Thanks！

Hi @Leo_W

These ICs are the AWG output amps AD8067, see:

Hi，

Picture 19 is written here, but I don't see it.

Thanks！
