ELECTRICAL CHARACTERISTICS (continued)
(AVDD = 2.7V to 5.25V, DVDD = 1.8V to AVDD, VAGND = 0, VDGND = 0, VREF = 2.5V (for AVDD = 2.7V to 5.25V), VREF = 4.096V (for
AVDD = 4.5V to 5.25V), RL = 10kΩ, CL = 100pF, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: For the force-sense versions, FB_ is connected to its respective OUT_, and VOUT (max) = VREF / 2, unless otherwise noted.
Note 2: Linearity guaranteed from decimal code 250 to code 4095 for the MAX5580A/MAX5581A (12 bit, A grade), code 40 to code
4095 for the MAX5580B/MAX5581B (12 bit, B grade), code 20 to code 1023 for the MAX5582/MAX5583 (10 bit), and code 5
to code 255 for the MAX5584/MAX5585 (8 bit).
Note 3: Represents the functional range. The linearity is guaranteed at VREF = 2.5V (for AVDD from 2.7V to 5.25V), and VREF =
4.096V (for AVDD = 4.5V to 5.25V). See the Typical Operating Characteristics section for linearity at other voltages.
Note 4: Guaranteed by design.
Note 5: The reference -3dB bandwidth is measured with a 0.1VP-P sine wave on VREF and with full-scale input code.
Note 6: DC crosstalk is measured as follows: outputs of DACA–DACD are set to full scale and the output of DACD is measured.
While keeping DACD unchanged, the outputs of DACA–DACC are transitioned to zero scale and the ∆VOUT of DACD
is measured.
