• Description: 3v/5v, 12-bit, Serial Voltage-output Dual Dacs With Internal Reference
• Manufacturer: Maxim Integrated Products, Inc.

ELECTRICAL CHARACTERISTICS—MAX5230 (continued)
(V
are at T
Note 1: Accuracy is guaranteed as shown in the following table:
Note 2: Offset is measured at the code closest to 10mV.
Note 3: Temperature coefficient is determined by the box method in which the maximum ∆V
Note 4: DC crosstalk is measured as follows: set DAC A to midscale, and DAC B to zero, and measure DAC A output; then change
Note 5: Accuracy is better than 1LSB for V
Note 6: Guaranteed by design, not production tested.
Note 7: R
