Hi team,
How does LDC1614-Q1 behaves when the oscillation amplitude exceed greater than 1.8V and the internal ESD clamping circuit will become active?
- Is there a hardware reliability risk? thermal, excessive current drawn?
- Oscillation will stop and the output will go all zero?
Datasheet description)
If the current drive results in the oscillation amplitude greater than 1.8V, the internal ESD clamping circuit will
become active. This may cause the sensor frequency to shift so that the output values no longer represent a
valid system state.If the current drive is set at a lower value, the SNR performance of the system will decrease,
and at near zero target range, oscillations may completely stop, and the output sample values will be all zeroes.
regards,
