Signal/Noise Ratio
**In simultaneous mode, both A/D converters operate at the same
time, sampling two channels at once. Each A/D converter is
capable of 100 kS/s, for an aggregate throughput of 200 kS/s.

†
In pseudo-differential mode, both the signal +in and –in are
connected to separate multiplexer channels. However, unlike
conventional differential circuits, only the +in side is sampled.
This requires that the –in side remain stable to within ±0.5 LSB
during conversion.
