AD7814 Silicon Anomaly ANOMALIES 1. High Current State and/or Incorrect Temperature from Power Cycling [er001] Background:
False temperature data is sometimes recorded by the AD7814 temperature sensor.
Issue:
Power cycling the AD7814 may put the part into a high current state and/or return an incorrect temperature value.
Workarounds:
To return the part back to normal operation, the SCLK pin must be clocked 16 times. Alternatively, perform a dummy temperature read. Either of these actions restores the part to normal operation.
Related Issues:
None.
