NOTES
11 LSB = 1 mV for 0 V to +4.095 V output range.
2Includes internal voltage reference error.
3These parameters are guaranteed by design and not subject to production testing.
4Very little sink current is available at the V
REF pin. Use external buffer if setting up a virtual ground.
5Settling time is not guaranteed for the first six codes 0 through 5.
6All input control signals are specified with t
R = tF
= 5 ns (10% to 90% of +5 V) and timed from a voltage level of 1.6 V.
7Power dissipation is a calculated value I
DD × 5 V.
Specifications subject to change without notice.
