LSB means Least Significant Bit. With VDD = 1.6V, one LSB is 390µV.

(2)

Assured by design, but not tested. Exceeding 50mA source current may result in device degradation.

(3)

Difference between TEMP1 and TEMP2 measurement; no calibration necessary.

(4)

Temperature drift: TEMP1 =

–2.024mV/°C, TEMP2 = –1.661mV/°C.
