TEMPERATURE MEASUREMENT
The DS600 analog temperature sensor measures it own temperature and provides these measurements to the
user in the form of an output voltage, V
characteristic is factory-calibrated for a typical output gain (ΔV/ΔT) of +6.45mV/°C and a DC offset (V
Its operating temperature range is -40°C to +125°C, corresponding to an output voltage range of 251mV to
1315mV. (V
+100°C temperature range and over the full 2.7V to 5.5V voltage range. Because the output voltage is positive for
the entire temperature range, there is no need for a negative supply.
Figure 2 shows the output voltage characteristic for the DS600.

Temperature Output. Outputs a voltage that is proportional to the die temperature in degrees
centigrade. In shutdown mode, this pin goes high-Z.

Shutdown. Power consumption and thermal sensor function are controlled through SD. This pin
functions as an active-high input pin. Driving this pin high puts the device in a low-power state and
discontinues thermal sensing.
