• RE: AD7172-2 channel sequencer

    Hi,

    Yes, you can have 4 channel in front of AIN0/AIN1 and another four in front of AIN2/AIN3. However, there are only 4 internal channels in AD7172-2, thus only 4 channels can be automatically sequenced. And the sequence will be from Channel 0 to Channel…

  • AD7172 sample rate question

    I'm a bit confused about the AD7172 sample rate in the datasheet. It says "The output data rates range from 1.25 SPS to 31.25 kSPS" and also says "has a maximum channel scan rate of 6.21 kSPS (161 µs) for fully settled data". I don't quite understand…

  • AD7172-2 Max Operating Temperature

    The data sheet lists max operating temp of 105C.  Is this part available with operating temp to 125C?

  • About AD7172-2 STATUS REGISTER

    By setting the DATA_STAT bit in the interface mode register,

    Is status register ahead of the data register or later?

    （Which is right,status register＋data register　or　data register＋status register?）

  • About AD7172-2 Input Impedance

    Hi, All.

    I want to know the input impedance at the time of buffer ON.

    For use with differential, it is good if you know the normal mode.

    Assumed to have rate is 500SPS.

    Best Regards,

  • AD7172-2 Precision Weigh Scale Issues

    I´m using AD7172-2 converter, with external amplifier, in bipolar mode input. The load cell is 30kg capacity and 2mV/V, and the excitation voltage is +5VDC (REF is +5VDC too to do ratiometric system). I attach the scheme.

  • AD7172-2 Sample rate not updating

    Hello

    I have mounted an AD7172-2 on my board and trying to vary it's sample rate but I am not able to.
