5 / 18 page 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 ∆VOUT 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 ∆VOUT for DAC A. Repeat the same measurement with DAC A and DAC B interchanged. DC crosstalk is the maximum ∆VOUT measured. Note 5: Accuracy is better than 1LSB for VOUT_ = 12mV to VDD - 180mV. Note 6: Guaranteed by design, not production tested. Note 7: RLOAD = ∞ and digital inputs are at either VDD or DGND.
