(V DD = +5V ±10%, V REFA = V REFB = 2.048V, R L = 10k
Ω
, C L = 100pF, T A = T MIN to T MAX , unless otherwise noted. Typical values are
at T A = +25°C (OS_ tied to AGND for a gain of +2V/V).)
Note 1: Accuracy is specified from code 6 to code 4095.
Note 2: Accuracy is better than 1LSB for V OUT _ greater than 6mV and less than V DD - 50mV. Guaranteed by PSRR test at the end
points.
Note 3: Digital inputs are set to either V
DD
or DGND, code = 0000 hex, R
L
= ∞ .
Note 4: SCLK minimum clock period includes the rise and fall times.
