• 求AD7712详细引脚介绍，AD7712是否有低通滤波和陷波的功能？

    求AD7712详细引脚介绍，AD7712是否有低通滤波和陷波的功能，第一次用AD7712，之前AD也用的少，网上资料都是英文的，有的说可编程滤波截止，有的说可编程第一个陷波，有点乱，谢谢！

  • AD7712: FAQs

    Q 

    In our application, some AD7712 use System Offset Calibration initiated, after
    the power-up, together with the device configuration, by the means of a single
    writing of the Configuration Register (0x8297A1). In our case, the calibration
    duration…

  • AD7712: Master clock

    Q 

    I would like to use sigma-delta converters for a
    multi-channel (48) acquisition application. There
    is a stringent need for synchronicity between
    each converter in our application.

    I am interested in using AD7712 converters since
    it features…

  • AD7712: power supply

    Q 

    If he wants to input +/-10V single-ended signal to AIN2. What power supply
    should he use? Single 5V, single 10V or +/-5V? I can not find very clear
    statement in the datasheet.

     

    A 

    For an analog input of +/-10V on the channel, a supply of +/-5V can…

  • AD7712: Noise spectral density

    Q 

    In AD7712 data sheet, pages 11 and 12, noise is specified as total rms value. I
    would like to know noise spectral density ( in particular for a 1kHz notch
    frequency selection and in a 1 mHz to 1 Hz bandwidth ). Have you got some
    specifications or…

  • AD7712 - measurement error

    I am using an AD7712 in a load cell application and am having difficulty obtaining a high level of accuracy across the entire input range of the converter.  My test method utilizes a precision full-bridge with setpoints at 0,0.5,1,1.5,2,2.5,3mV/V and across…

  • AD7712的DRDY问题

    在使用的过程中，采用单端输入，外部10MHz时钟，发现DRDY的高电平持续时间不一致，持续时间长的达到20MS，短的也有5MS。这个现象可以改进吗？该如何操作。

  • AD7712: Variation of input impedance over temperature

    Q 

    Can you tell me the variation in input resistance (Rint) and variation
    in input capacitance (Cint) over tempearture?

     

    A 

    Rint and Cint were not characterized over temperature for AD7712 so I regret
    that we have no data
    to provide with regards to…

  • AD7712: /DRDY stays high after 1st read

    Hello,

    This is about receiving data register contents from AD7712.

    The problem is that AD7712 cannot set /DRDY pin low after 1st read on data register. I would like my system to read data register continuously.

    The 1st read terminated when AD7712 turned…

  • AD7712 Output Data are always low

    Hello,

    This is about receiving data register contents from AD7712.

    First of all, I am using an Automatic Test Equipement to evaluate the AD7712. The ATE acts as a microcontroller to drive and read data from the ADC.  From the ATE we have also the supply…
