TEMPERATURE MEASUREMENT

The VTEMP output pin is a voltage output for temperature monitor-

ing purposes. This output voltage is ratiometric to the supply. For

maximum accuracy, an initial calibration at a known temperature is

recommended.

A temperature measurement can be extracted from the measure-

ment of the VTEMP pin by the following equation:

TVTEMP=VTEMP−VTEMPCAL−TCVTEMP×TCAL

TCVTEMP

(18)

where:

TVTEMP is the calibrated temperature of the sensor.

VTEMP is the output of the VTEMP pin.

VTEMP

CALis the output of the VTEMP pin at the calibration tempera-

ture.

TCVTEMP is the temperature coefficient of the sensor as shown in

Table 8.

TCAL is the temperature at which the calibration was performed.

VTEMP must be left disconnected when not in use.
