32-Channel, 16-Bit, Voltage-Output
DACs with Serial Interface
ELECTRICAL CHARACTERISTICS—MAX5734 (-2.5V to +7.5V Output Voltage Range)
(continued)
(AVCC = +7.75V to +8.25V, AVDD = +5V ±5%, DVDD = +2.7V to AVDD, VSS = -2.75V to -3.25V, AGND = DGND = REFGND = GS = 0,
program the offset DAC to 4000hex. VREF = +3.0V, RL = ∞, CL= 50pF referenced to ground, TA = TMIN to TMAX, unless otherwise
noted. Typical values are at TA = +25°C.)
