50 The ADT7310/ADT7410 is a temperature sensor wi
51 -55°C to +150°C. It has a high accuracy of +
52 resolution of 13 bits (0.0625°C) or 16 bits (
53 INT pin to indicate that a minimum or maximum
54 exceeded, as well as a critical temperature (C
55 critical temperature set point has been exceed
56 common hysteresis of 0°C - 15°C and a fault
57 Both pins can individually set to be active-lo
58 device can either run in comparator mode or in
59 continuous temperature sampling, as well as sa
60 second or even just get one sample on demand f
61 completely power down its ADC, if power manage
62
63 The ADT7320/ADT7420 is register compatible, th
64 package, a slightly narrower operating tempera
65 a better accuracy (0.25°C instead of 0.50°C.

67 The difference between the ADT7310/ADT7320 and
68 interface, the ADT7310 and ADT7320 use SPI whi
69 I2C.
