This is specified by characterization but is not production tested.
NOTES: 14. The ACT bit is latched on EN↓.
15. Reference feedthrough is measured at any DAC output with an input code = 00 hex with a V
ref
input = 1 V dc + 1 V
PP
at 10 kHz.
16. Channel-to-channel isolation is measured by setting the input code of one DAC to FF hex and the code of all other DACs to 00 hex
with V
ref
input = 1 V dc + 1 V
PP
at 10 kHz.
17. Reference bandwidth is the –3 dB bandwidth with an ideal input at V
ref
= 1.25 V dc + 2 V
PP
and with a digital input code of full-scale
(range set to × 1 and V
DD
= 5 V).
