• AD7707:input impedance and currents

    I´ve got some questions about the specifications of the AD7707. I´m working
    actually with the low level inputs. I didn´t found clearly values about the
    input impedance or input currents in buffered or unbuffered mode in the data
    sheet. Could…
  • RE: AD7707 and reference voltage

    Hi,

    I would suggest to use a stable external reference voltage for your other inputs. So make sure that your current source is stable if you intended to use the same reference voltage for this. Any variation in reference voltage may results errors or…

  • AD7707要停产了吗

    AD7707要停产了吗?现在市场卖家说这款产品封装要停产了,改其他封装,请问下有没有哪款产品可以代替,谢谢!

  • AD7707的采样速度问题

    我使用AD7707设计产品,晶振4.9152M,使用模拟开关8通道切换,每通道工作在50HZ,但是每各通道的增益不同,目前已经能读到数据,但是在速度方面不高,115200的时候只能4次/秒,但是按照计算115200BPS,按照每次发送8个字节指令读取,返回7个数据指令,应该可以做到10次/秒,我不是很清楚问题出在哪,我如果设置采集速度为250次/秒,也只能到5次左右,另外我没有找的AD7707哪地方有个CODE寄存器,附件是读写和设置程序,请帮我看下是什么问题,以下是设置程序:

  • AD770x经典仪表转换器常见问题解答

    AD7705和AD7706均为完整16位、低成本、Σ-Δ型ADC,适合直流和低频交流测量应用。其具有低功耗(3 V时最大值为1 mW)特性,因而可用于环路供电、电池供电或本地供电的应用中。片内可编程增益放大器提供从1至128的增益设置,无需使用外部信号调理硬件便可接受低电平和高电平模拟输入。

    AD7705拥有两个差分通道,而AD7706则拥有一个差分通道和两个伪差分通道。在定制比率应用器件时,差分基准电压输入还能提供极大的灵活性。

    AD7707是一款适合低频测量应用的完整模拟前端。这款3通道器件既可以直接从传感器接受低电平输入信号…

  • AD7790: Shift signals

    Sensor output is amplified so that signal lies between -3 and +3 V. System
    voltage is 3 V, -3V available from a voltage converter.
    Is it possible in some way to use the AD7790 as ADC in that case? What other
    possibilities are there to…
  • 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…
