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.
5All 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.
6The settling time specification does not apply for negative going transitions within the last 6 LSBs of ground. Some devices exhibit double the typical settling time in this 6 LSB region.
7Power Dissipation is calculated I
DD × 5 V.
Specifications subject to change without notice.
