Hello,
I am using the LM32401 see schematic attached:
LMH34204 + LMH6552 driving the RFSOC.pdf
1. Power to ADC is coming first -so there is 0.7V the common mode voltage)
2. Power of +5V, -5V and 3.3V come later.
The problem that I encounter is that VOC that should be 1.1V is becomes around zero and the output is oscillating. (The deferential voltage on R1 is 1.2V.)
Any comment ?
Sincerely,
Giora
