Hello,
I am using the VCOM output as the positive bias for an amplifier and then feeding the output of the amplifier to VREFP. Whenever I probe the VCOM output, my voltage rapidly decreases and does not come back up to AVDD/2 unless I toggle power. Is this a normal condition? This is happening without driving the ADC as well. I have 5V on AVDD, 1.8V on DVDD, and 3.3V on IOVDD.
Thank you,
Eduardo
