Maxim Integrated 

Low-Power, Quad, 12-Bit Voltage-Output DAC

with Serial Interface

ELECTRICAL CHARACTERISTICS (continued)

(VDD = +5V ±10%, AGND = DGND = 0V, REFAB = REFCD = 2.5V, 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 1.0LSB for VOUT = 6mV to VDD - 60mV, guaranteed by PSR test on end points.

Note 3: RL = ∞, digital inputs at DGND or VDD.
