+5V/+3V, 12-Bit, Serial, Force/Sense DACs
with 10ppm/°C Internal Reference
TIMING CHARACTERISTICS—MAX5123 (+3V)
(VDD = +3V ±10%, AGND = DGND, 33nF capacitor at REFADJ, internal reference, RL = 5kΩ, CL = 100pF, output amplifier connected
in unity-gain, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

Note 2: Offset is measured at the code closest to 10mV.
Note 2: The temperature coefficient is determined by the “box” method, in which the maximum ∆VOUT over the temperature range
is divided by ∆T and the typical reference voltage.
Note 4: Accuracy is better than 1.0LSB for VOUT = 10mV to (VDD - 180mV). Guaranteed by PSR test on end points.
Note 5: RLOAD = ∞and digital inputs are at either VDD or DGND.
