50 The ADT7310/ADT7410 is a temperature sensor with rated temperature range of
51 -55°C to +150°C. It has a high accuracy of +/-0.5°C and can be operated at a
52 resolution of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an
53 INT pin to indicate that a minimum or maximum temperature set point has been
54 exceeded, as well as a critical temperature (CT) pin to indicate that the
55 critical temperature set point has been exceeded. Both pins can be set up with a
56 common hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events.
57 Both pins can individually set to be active-low or active-high, while the whole
58 device can either run in comparator mode or interrupt mode. The ADT7410 supports
59 continuous temperature sampling, as well as sampling one temperature value per
60 second or even just get one sample on demand for power saving. Besides, it can
61 completely power down its ADC, if power management is required.
63 The ADT7320/ADT7420 is register compatible, the only differences being the
64 package, a slightly narrower operating temperature range (-40°C to +150°C), and
65 a better accuracy (0.25°C instead of 0.50°C.)
67 The difference between the ADT7310/ADT7320 and ADT7410/ADT7420 is the control
68 interface, the ADT7310 and ADT7320 use SPI while the ADT7410 and ADT7420 use
74 Since the device uses one hysteresis value, which is an offset to minimum,
75 maximum and critical temperature, it can only be set for temp#_max_hyst.
76 However, temp#_min_hyst and temp#_crit_hyst show their corresponding
78 The device is set to 16 bit resolution and comparator mode.
