NOTES
1All 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.
21 LSB = 1 mV for 0 to +4.095 V output range.
3Includes internal voltage reference error.
4These parameters are guaranteed by design and not subject to production testing.
5Very little sink current is available at the REFOUT pin. Use external buffer if setting up a virtual ground.
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.
Specifications subject to change without notice.
