(VDCIN = +48V, TA = TMIN to TMAX, unless otherwise noted, where TMIN = -40°C and TMAX =+125°C. Typical values are at TA = +25°C.

Operation is with the recommended application circuit.) (Note 5)

Note 5: Unless otherwise noted, limits are 100% production tested at TA = +25°C. Limits over the operating temperature range and

relevant supply voltage range are guaranteed by design and characterization.

Note 6: Acquisition mode (ADC conversions) is entered when the SCAN bit is set and ends when SCANDONE is set. With the

typical acquisition duty-cycle very low, the average current (IDCIN) is much less than IDCMEAS. Total supply current during

communication: IDCIN = IDCCOMM + IDCSTBY.

Note 7: Range over which measurement settling time and accuracy is guaranteed.

Note 8: VCELLn = VCn - VCn-1, VCELLn = VCELLn-1, and VDCIN = 12 x │VCELLn │ (9V min).

Note 9: Guaranteed by design and not production tested.

Note 10: As measured during specified diagnostic mode; 5V full-scale for unipolar mode measurements and 2.5V full-scale for bipolar

measurements.

Note 11: ISHDNL measured with VSHDNL = 0.3V, STOP characters, zero idle time, VRX_PEAK = 3.3V.

Note 12: Charge pump efficiency = δILOAD/δISUPPLY, where ILOAD is applied from HV to AGND, δILOAD = 5mA, and δISUPPLY = IDCIN

(for ILOAD = 5mA) - IDCIN (for ILOAD = 0).

Note 13: Differential signal (VRXP - VRXN) where VRXP and VRXN do not exceed a common-mode voltage range of ±25V.

Note 14: In daisy-chain applications, the bit time of the second STOP bit may be less than specified to account for clock-rate variation

and sampling error between devices.

Note 15: Maximum limited by application circuit.

Note 16: Fall time measured 90% to 10%; rise time measured 10% to 90%.

Note 17: VDDL = VDDL2 for lower port; VDDL = VDDL3 for upper port.
