Note 1: INL and DNL are measured with R
L
referenced to ground. Nonlinearity is measured from the first code that is greater than
or equal to the maximum offset specification to code FF hex (full scale). See
DAC Linearity and Voltage Offset
section.
Note 2: V
REF
= 4Vp-p, 10kHz. Channel-to-channel isolation is measured by setting one DAC’s code to FF hex and setting all other
DAC’s codes to 00 hex.
Note 3: V
REF
= 4Vp-p, 10kHz. DAC code = 00 hex.
Note 4: Guaranteed by design, not production tested.
Note 5: Output settling time is measured from the 50% point of the rising edge of CS to 1/2LSB of V
OUT
’s final value.
Note 6: Digital crosstalk is defined as the glitch energy at any DAC output in response to a full-scale step change on any other
DAC.
Note 7: If LDAC is activated prior to CS’s rising edge, it must stay low for t
LDAC
or longer after CS goes high.
Note 8: When DOUT is not used. If DOUT is used, f
CLK
max is 4MHz, due to the SCLK to DOUT propagation delay.
Note 9: Serial data clocked out at SCLK’s rising edge (measured from 50% of the clock edge to 20% or 80% of V
DD
).
Note 10: Serial data clocked out at SCLK’s falling edge (measured from 50% of the clock edge to 20% or 80% of V
DD
).
