1.
Valid for ambient operating temperature: TA = –40 to +125 °C; VDD = 2.25 V to 3.6 V (except where noted).
2.
Typical numbers are for TA = +25 °C; VDD = 3.0 V
3.
Not tested, guaranteed by design.
4.
Accuracy measurements made at resolutions > 10 bits.
5.
Above 105 °C, temperature accuracy is guaranteed for VDD ≥ 2.50 V.
6.
SMBus timeout min and max are valid for TA = –30 to +125 °C.
