(1)
Settling time is the time for the output signal to remain within
±0.5LSB of the final measured value for a digital input code change of 000
hex to 3FF hex or 3FF hex to 000 hex.
(2)
Reference feedthrough is measured at the DAC output with an input code = 000 hex and a Vref input = 2.048Vdc + 1Vpp at 1kHz.
