MAX5170/MAX5172
Low-Power, Serial, 14-Bit DACs
with Voltage Output
_______________________________________________________________________________________ 5
Note 1: INL guaranteed between codes 40 and 16383.
Note 2: Offset is measured at the code that comes closest to 10mV.
Note 3: Accuracy is better than 1.0 LSB for V OUT = 10mV to V DD - 180mV. Guaranteed by PSR test on end points.
Note 4: R L = open and digital inputs are either V DD or DGND.
Note 5: INL guaranteed between codes 80 and 16383.

(V DD = 2.7V to 3.6V, V REF = 1.25V, OS = AGND = DGND, R L = 5k Ω , C L = 100pF referenced to ground, T A = T MIN to T MAX , unless
otherwise noted. Typical values are at T A = +25°C).
