Hello,

The INTB pin can be configured to notify the host of several different changes in system status. The assertion/de-assertion of the INTB pin will depend on what it is configured for.

What is the INTB pin configured for in your system?

Best regards,

Nicole

Hello,

In single-channel continuous conversion mode Data Ready will occur when the conversion is complete. This will cause INTB to assert, and reading the Status register will de-assert INTB. Reading the DATA0 register will not cause INTB to de-assert.

For further reference, the LDC1312, LDC1314, LDC1612, LDC1614 Sensor Status Monitoring application note goes into this in more detail.

Best regards,

Nicole
