1. Guaranteed by design.
2. V_REF is normally tied to V_OFFSET through 50 ohms. If V_REF is used to provide dc offset to other circuits, it should first be buffered
3. ENCODE driven by single-ended source; ENCODE bypassed to ground through 0.01 µ F capacitor.
4. ENCODE may also be driven differently in conjunction with ENCODE.
