Analog switch (SPST) and SPDT control input
ADC data-ready output
General-purpose output
PWM output
Alarm output
SPI pass-through
Internal and External (Remote)
Temperature Sensors
An internal transistor or a remote transistor (or diode) is
used with the ADC and a programmable current source
to measure the ambient temperature. Depending on the
method, either two or four currents are passed through
the PN junction. The voltage across the PN junction is
measured at each current. For each current, the voltage
across a series resistor is also measured. Measuring the
voltage across the resistor allows the user to determine
the precise current ratios. A microcontroller can then
use the diode equation to calculate the temperature.
The four-current method eliminates errors caused by
parasitic resistance in series with the diode, which
increases the apparent voltage across the PN junction.
When measuring temperature using the internal transis-
tor for a sensor, the two-current method is usually ade-
quate although the four-current method can also be
used. Refer to Application Note 4296:
