Description
Decouple with 1 µF capacitor to AVSS. Do not inject noise into this pin
as it directly impacts ADC conversion noise.
Pin must be tied to high quality ground, usually a solid PCB plane.
Differential Zero Gating Input.
If single ended signal sources are used, the unused terminal (either
ZERO+ or ZERO-) must be tied to an appropriate DC bias.
