+3V, Quad, 12-Bit Voltage-Output DAC
with Serial Interface
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +3.0V to +3.6V, AGND = DGND = 0V, REFAB = REFCD = 1.25V, RL = 5kΩ, CL = 100pF, TA = TMIN to TMAX, unless otherwise
noted. Typical values are at TA = +25°C. Output buffer connected in unity-gain configuration (Figure 9).)

Note 1: Guaranteed from code 11 to code 4095 in unity-gain configuration.
Note 2: Accuracy is better than 0.5LSB for VOUT = 6mV to VDD - 80mV, guaranteed by PSR test on endpoints.
Note 3: Remains operational with supply voltage as low as +2.7V.
Note 4: RL = ∞, digital inputs at DGND or VDD.
