NOTES
1
1 LSB = 1 mV for 0 V to +4.095 V output range.
2
Includes internal voltage reference error.
3
These parameters are guaranteed by design and not subject to production testing.
4
Very little sink current is available at the V
REF
pin. Use external buffer if setting up a virtual ground.
5
Settling time is not guaranteed for the first six codes 0 through 5.
