Note 1: All voltages are referenced to ground. Current into IC is positive, out of the IC is negative.
Note 2: Secondary power supply is used to support optional variable power-supply feature of the XFP module. If VCC2 is not used,
(i.e., signal conditioners using 3.3V supply) VCC2 should be connected to the VCC3.
Note 3: Input signals (i.e., TX-D, MOD-DESEL, and P-DOWN/RST have internal pullup resistors.
Note 4: Guaranteed by design. Simulated over process and 50µA < IBMD < 1500µA.
Note 5: CB—total capacitance of one bus line in picofarads.
Note 6: EEPROM write begins after a stop condition occurs.
Note 7: This is the maximum and minimum voltage on the MODSET and BIASSET pins required to meet accuracy and drift specifi-
cations.
Note 8: For VTHRSET, offset may be as much as 10mV.
Note 9: This is the uncalibrated offset provided by the factory; offset adjustment is available on this channel.
Note 10: % FS refers to calibrated FS in case of internal calibration, and uncalibrated FS in the case of external calibration.
Uncalibrated FS is set in the factory and specified in this data sheet FS (factory). Calibrated FS is set by the user, allowing
a change in any monitored channel scale.
Note 11: See the Monitor Channels section for more detail or VCC2 and VCC3 selection.
