For minimum noise, the sensor measurement should be performed after the sensor amplitude has stabilized. The LDC1312/LDC1314 provides an adjustable sensor startup timing per channel. The timing can be varied from 1.2 µs to >26.2 ms by setting the SETTLECOUNTx register. Sensors with lower resonant frequencies or higher Qs may require additional time to stabilize.
Refer to Settling Time for details on the LDC1312/LDC1314 configuration and details on the setting conversion interval.
The LDC1312/LDC1314 can be configured with a faster sensor activation, or to use a lower current sensor activation. Refer to Sensor Activation for details on this capability.
The LDC1312/LDC1314 provides an internal filter to attenuate interference from external noise sources. Refer to Input Deglitch Filter for information on configuration on the deglitch filter.
