LDC1614: Sensor amplitude error thresholds

Part Number: LDC1614
Other Parts Discussed in Thread: LDC1314, LDC1312, LDC1612,

What are the Amplitude Low Error and Amplitude High Error threshold levels?

Thanks!

  • Hello,

    The levels are approximately 1.2V and 1.8V respectively. You can refer to the following application note for more information on using the Status register:

  • A data value of 0x0000000 = under range
    A data value of 0xFFFFFFF = over range
  • Hello,

    To clarify:

    • Amplitude Low Error (ERR_ALE) occurs when the sensor oscillation amplitude is <1.2V
    • Amplitude High Error (ERR_AHE) occurs when the sensor oscillation amplitude is >1.8V
    • Conversion Over Range Error (ERR_OR) occurs when the sensor frequency exceeds the reference frequency. This would max out DATAx and give a value of 0xFFFFFFF
    • Conversion Under Range Error (ERR_UR) occurs when you are using the CHx_OFFSET register and the resulting DATAx value would be a negative number. 

    You can find a deeper description of these error conditions as well as the other STATUS reporting bits in the application note listed above: www.ti.com/.../SNOA959
