Temperature Sensor - Analog Devices ADRV9005 Reference Manual

Reference Manual
AUXILIARY CONVERTERS AND TEMPERATURE SENSOR
The AuxADC clock rate is set to 30.72 MHz (or close when the ADRV9001 ARM system clock is changed) to get the best ADC performance.
No on-chip calibrations are executed for the AuxADC. The ADC accuracy is limited to the accuracy of the supply reference. A simplified
procedure is performed to measure and account for the AuxADC gain and offset errors. These AuxADC gain and offset errors are used to
compensate for the AuxADCs measure results.

TEMPERATURE SENSOR

The ADRV9001 device features one instance of an on-chip temperature sensor that measures the temperature on the die. The temperature
sensor uses an ADC similar to the AuxADC. However, it is a separate instantiation and has no connections to a device pin. The temperature
sensor functions during the normal operation mode as well as the deep-sleep or monitor mode of the device.
The ADRV9001 internal microprocessor performs the initialization of the temperature sensor hardware without any user interaction. An API
function "adi_adrv9001_Temperature_Get()" retrieves the current temperature measurement result, which is in celsius.
As the temperature sensor clock rate can depend on the user-configured profile, the measurement time depends on the user profile and other
factors such as the number of average ADC performed. It usually takes several milliseconds to complete one measurement.
Note: The obtained temperature measurement represents an estimation, with limited accuracy.
