Hi,
page 25 of the datasheet says:
If the output path is AC-coupled, letting the VOCM control pin float is usually preferred to obtain a midsupply default VOCM bias with no external elements. To limit noise, place a 0.1-
μF decoupling capacitor on the VOCM pin to ground.
On the other hand, page 30:
The CM input controls the output common-mode voltage. CM has no internal biasing network and must be driven by an external source or resistor divider network to the positive power supply.
Can VOCM be floated with bypass for single +5 V supply with desired +2.5 V output common mode? (inputs and outputs AC-coupled)
Best regards,
KJ
