• 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

    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

    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

    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.

     

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

  • AD7712: Noise spectral density

    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

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

     

    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…
