Hi,
I redesigned a Board I made earlier this year. I didnt change anything in the schematic that would affect this. However the Waveform output for my primary coils looks like this:
I meassured the output of P1 and P2 against 0V which showed the right output, as seen below. The amplitude of the resulting LVDT-Voltage is 2.5V
The Schematic is exactly the same as suggested by TI. On the Top of C1 and C2 are connections to P1 and P2. On the left there are only the pins for the primary coil. on the right side is another usage of the consistent 2.5V
The fluctuations on the primarycoil pins can be stopped by plugging in the debugger and stopping the programm, however the same program is working on the old board.
Do you have any idea/suggestion on how to fix that issue?
Regards, Paul
