(1)
LSB means least significant bit. With VDD (REF) = +2.5V, 1LSB is 610μV.
(2)
Ensured by design, but not production 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
–2.1mV/°C.
