• RE: Using AD7147 Evaluation Board with AD7147A

    Hi Dave, The AD7147 and AD7147A parts are functionally compatible, just in different packages.

  • What is the AD7147A digital I/O capacitance?

    Looking for pin capacitance for I2C the Logic I/O for the AD7147A.

    Don't see it listed on the data sheet.

     

  • AD7147 Multiple cap sensors in one setup

    I am using an AD7147 capacitive sensor chip to detect objects inserted between parallel plates. To extend the setup, I would need to use several AD7147 chips to do the job (each one can measure up to 13 channels). However, I am worried that the AC-shield…

  • AD7147 FIFO's do not function

    I have been using the AD7147 capacitance sensor to detect objects between two parallel copper plates. I stumbled on the following strange fenomenon:

    - Reading the conversion data from the chip is no problem. I read the following registers through my…

  • I2C addressable capacitance-to-digital converter

    My customer would like to connect 2 devices AD7151 to the same I2C line. It
    seems this is not possible, isn’t it?
    Customer do not need more inputs, this is just for security and redundancy
    reasons, it must be two separate chips. Is this…
  • AD7147 real capacitance reading and resolution

    Hi everybody,

    i am using the AD7147.

    i have some questions about offsets and fF per count.

    i understand that the best way to use the sensor is around the mid count 32750, using offset compensation to be in that range.

    i had read that offset is .32pF…
