1 Temperature range is −40°C to +125°C.
2 See Terminology section.
3 Sample tested during initial release to ensure compliance.
4 Guaranteed no missed codes to 12 bits.
5 VIN− or VIN+ must remain within GND/VDD.
6 VIN− = 0 V for specified performance. For full input range on VIN− pin, see Figure 28 and Figure 29.
7 For full common-mode range, see Figure 24 and Figure 25.
8 Relates to Pin DCAPA or Pin DCAPB.
