MAX5150/MAX5151
Low-Power, Dual, 13-Bit Voltage-Output DACs
with Serial Interface
_______________________________________________________________________________________ 5
Note 4: Accuracy is specified from code 20 to code 8191.
Note 5: Accuracy is better than 1LSB for V
OUT
greater than 6mV and less than V
DD
- 80mV. Guaranteed by PSRR test at the end
points.
Note 6: Digital inputs are set to either V
