LDC1314: About I2c scan test for ldc1314

Part Number: LDC1314

I made a circuit board using LDC1314. I used I2C scanner to check the address of the device. As soon as I turn on the power, I get addresses "0x2A" and "0x2B". But after a while, I can't get both addresses. What is the cause of this?

    Hello, 

    The address of the LDC1314 is set by the ADDR pin and should only show as either 0x2A or 0x2B depending on the state of that pin. On your board, how do you have the ADDR pin connected? Tied HI/LO or to an MCU?
