Note 1: Reduced digital code range (code 00 hex to code F0 hex) due to swing limitations when the output amplifier is loaded.
Note 2: Gain error is: [100 (V
F0,meas
- ZCE - V
F0,ideal
) / V
REF
]. Where V
F0,meas
is the DAC output voltage with input code F0 hex,
and V
F0,ideal
is the ideal DAC output voltage with input code F0 hex (i.e., V
REF
·
240 / 256).
Note 3: Output settling time is measured from the 50% point of the falling edge of WR to ±1/2LSB of V
OUT
’s final value.
Note 4: Channel-to-channel isolation is defined as the glitch energy at a DAC output in response to a full-scale step change on any
other DAC output. The measured channel has a fixed code of 80 hex.
Note 5: Digital feedthrough is defined as the glitch energy at any DAC output in response to a full-scale step change on all eight
data inputs with WR at V

Note 7: Timing measurement reference level is (V

) / 2.
Note 8: If LDAC is activated prior to WR’s rising edge, it must stay low for t
LD
(or longer) after WR goes high.
