20*4882a593SmuzhiyunDescription
21*4882a593Smuzhiyun-----------
22*4882a593Smuzhiyun
23*4882a593SmuzhiyunThe MAX1619 is a digital temperature sensor. It senses its own temperature as
24*4882a593Smuzhiyunwell as the temperature of up to one external diode.
25*4882a593Smuzhiyun
26*4882a593SmuzhiyunAll temperature values are given in degrees Celsius. Resolution
27*4882a593Smuzhiyunis 1.0 degree for the local temperature and for the remote temperature.
28*4882a593Smuzhiyun
29*4882a593SmuzhiyunOnly the external sensor has high and low limits.
30*4882a593Smuzhiyun
31*4882a593SmuzhiyunThe max1619 driver will not update its values more frequently than every
32*4882a593Smuzhiyunother second; reading them more often will do no harm, but will return
33*4882a593Smuzhiyun'old' values.
