(1) LSB means Least Significant Bit. With VDD/REF pin = +1.6V, one LSB is 391 μV.
(2) Specified by design, but not tested. Exceeding 50 mA source current may result in device degradation.
(3) Difference between TEMP1 and TEMP2 measurement; no calibration necessary.
(4) Temperature drift is –2.1 mV/°C.
