LDC2112: Questions of LDC2112

Part Number: LDC2112

Hi Ti,

Here're some questions of LDC2112:

1.We use the 100kHz I2C standard in our system. What I2C version is LDC2112 use?

Because we would like to confirm the specification of timing in LDC2112.

2.In LDC2112 datasheet could find the 2 channels supply current.

What if I use only one channel, what will the current be?

Thank you!

Scott

    Hello Scott, 

    The maximum speed of the I2C for the LDC2112 is 400kHz. 

    The supply current for only 1 channel in low power mode is typically 9uA. For normal mode, figures 5 & 6 in section 6.8 of the datasheet show the supply current of one channel at 40SPS. Note that this can vary depending on your sensor/implementation as well. 

    Hope this helps,
