+3V, Quad, 12-Bit Voltage-Output DAC with Serial Interface

Maxim Integrated 

+3V, Quad, 12-Bit Voltage-Output DAC

with Serial Interface

TIMING CHARACTERISTICS

(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).)
