1 C1 (Pin 10) tied to GND through a 0.01 μF capacitor.
2 VREF is normally tied to VOFFSET through 50 Ω. If VREF 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 a 0.01 μF capacitor.
4 ENCODE may also be driven differentially in conjunction with ENCODE; see the Encoding the AD9042 section for details.
