Low-Power, Quad, 10-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).)
