ELECTRICAL CHARACTERISTICS (continued)

(DVDD = AVDD = +2.7V to +3.6V (MAX1233), DVDD = AVDD = +4.75V to +5.25V (MAX1234), external reference VREF = 2.5V

(MAX1233), VREF = 4.096V (MAX1234); fSCLK = 10MHz, fSAMPLE = 50ksps, 12-bit mode, 0.1ÂµF capacitor at REF, TA = -40Â°C to

+85Â°C, unless otherwise noted. Typical values are at TA = +25Â°C.)

Note 8: The offset value extrapolated from the range over which the INL is guaranteed.

Note 9: Output settling time is measured by stepping from code 5 to 255, and from code 255 to 5.

Note 10: Actual output voltage at full scale is 255/256 Ã VREFDAC.

Note 11: Resistance is open when configured as GPIO or in shutdown.

Note 12: AVDD and DVDD should not differ by more than 300mV.

Note 13: When configured as GPIO.
