ANA#27

Digital Temperature Sensor Having Higher Error

Revision(s) Affected:

AWR1843 ES1.0

Description:

Due to the single-ended nature of the digital temperature sensors, as compared to the differential design of analog temperature sensors (that is, TX, RX, and PM), it is vulnerable to noise and can have higher error than the analog temperature sensors.

Workaround(s):

Use only the analog temperature sensor values (TX and RX) in the algorithm. The digital temperature sensor value can be ignored.
