NOTES
1
All input control signals are specified with tr = tf = 5 ns (10% to 90% of +5 V) and timed from a voltage level of 1.6 V.
2
1 LSB = 1 mV for 0 V to +4.095 V output range.
3
Includes internal voltage reference error.
4
These parameters are guaranteed by design and not subject to production testing.
5
The 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.
Specifications subject to change without notice.
