I am trying to modifying the EVAL-ADHV4702-1 evaluation board to single power supply (0-220V) mode, to amplify a 0V-2V triangle voltage waveform to 0-200V voltage:
1. For the power management part (the flyback converter on board), I am going to connect both VEE_TRANSFORMER and VEE pins to AGND at P4, and connect VCC_TRANSFORMER to VCC at P1, while leave P5 open. By doing so, I should be able to get a 220V VCC and 0V VEE.
2. For the opamp part, I am going to connect VMID to AGND by P2 to get the full positive amplification from 2V to 200V.
Is this correct?
I see the user guide suggest to connect VMID to (VCC+VEE)/2, which is 110V for my case. But if I do so for the 2V input and 100V/V Av, the output will saturate at 220VCC-110VMID = 110 V, instead of a expected 200V output, right?
Please confirm or correct me if I made any mistakes.
Thank you so much for your help!
