Note 1: Guaranteed from code 5 to code 255.

Note 2: The offset value extrapolated from the range over which the INL is guaranteed.

Note 3: MAX5382 tested at V

= +5V ±10%.

Note 4: MAX5380 tested at V

= +3V ±10%, MAX5381 tested at V

= 5V ±10%.

Note 5: Actual output voltages at full scale are 255/256 x V

Note 6: Output settling time is measured by taking the code from code 5 to 255, and from code 255 to 5.

Note 7: Guaranteed by design.
