Tool/software:
We are planning on using a PGA870 with VS+ at 5V. So VMID2 output should be at 2.5V.
We would like to use VMID2 as the VOCM input to an opamp that feeds it. The input to that stage is bipolar and we need to offset it be be from 0 to 5V.
But the PGA870 datasheet makes the following statement:
So it says "don't use it" but then go ahead as long as you don't draw too much current.
So can we safely use it to drive the VOCM pin of an opamp, which will draw much less than 200 uA?
If the VMID2 pin is not intended to be used, why does it exist?
