MAX UNITS

Note 1: All voltages are referenced to ground. Current into the IC is positive, and current out of the IC is negative.

Note 2: Inputs are at supply rail. Outputs are not loaded.

Note 3: This parameter is guaranteed by design.

Note 4: Full scale is user programmable.

Note 5: A temperature conversion is completed and MOD1 DAC, MOD2 DAC, APC1 DAC, and APC2 DAC values are recalled

from the LUT and VCC has been measured to be above VCC LO alarm, if the VCC LO alarm is enabled.

Note 6: I2C interface timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I2C stan-

dard mode.

Note 7: CB—Total capacitance of one bus line in pF.

Note 8: EEPROM write begins after a STOP condition occurs.
