ELECTRICAL CHARACTERISTICS—MAX537 (continued)

(VDD = +5V, VSS = -5V, REFAB/REFCD = 2.5V, AGND = DGND = 0V, RL = 5kΩ, CL = 100pF, TA = TMIN to TMAX, unless

otherwise noted. Typical values are at TA = +25°C.)

Note 2: Guaranteed by design.

Note 3: Crosstalk is defined as the glitch energy at any DAC output in response to a full-scale step change on any other DAC.

Note 4: Digital inputs at 2.4V; with digital inputs at CMOS levels, IDD decreases slightly.

Note 5: All input signals are specified with tR = tF ≤ 5ns. Logic input swing is 0 to 5V.

Note 6: Serial data clocked out of SDO on SCK’s falling edge. (SDO is an open-drain output for the MAX536. The MAX537’s SDO

pin has an internal active pullup.)

Note 7: Serial data clocked out of SDO on SCK’s rising edge.

Note 10: When disabled, SDO is internally pulled high.
