With VREF equal to +2.5V, one LSB is 610µV. (2) Ensured by design, but not tested. Exceeding 50mA source current may result in device degradation. (3) Difference between TEMP0 and TEMP1 measurement. No calibration necessary. (4) Temperature drift is –2.1mV/ °C. ELECTRICAL CHARACTERISTICS (Cont.) At TA = –40°C to +85°C, +VDD = +2.7V, VREF = 2.5V external voltage, I2C bus frequency = 3.4MHz, 12-bit mode and digital inputs = GND or +VDD, unless otherwise noted.
