MAX5232/MAX5233
3V/5V, 10-Bit, Serial Voltage-Output Dual DACs
with Internal Reference
_______________________________________________________________________________________ 5
Note 1: Accuracy is guaranteed as shown in the following table:
Note 2: Offset is measured at the code closest to 12mV.
Note 3: Temperature coefficient is determined by the box method in which the maximum
∆V
OUT over the temperature range is
divided by ∆T.
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
DAC B to full scale, and measure ∆V
OUT for DAC A. Repeat the same measurement with DAC A and DAC B interchanged.
DC crosstalk is the maximum ∆V
OUT measured.
Note 5: Accuracy is better than 1LSB for V OUT_ = 12mV to V DD - 180mV.
Note 6: Guaranteed by design, not production tested.
Note 7: R
LOAD
= ∞ and digital inputs are at either V
DD
or DGND.
