21 The Texas Instruments TMP108 implements one temperature sensor. An alert pin
26 The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0
27 degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
28 operating temperature has a minimum of -55 C and a maximum of +150 C.
35 the TMP108 has a one-shot mode where the device is normally shut-down. When a
36 one shot is requested the temperature is read, the result can be retrieved,
40 The driver provides the common sysfs-interface for temperatures (see
