• RE: Ask questions about AD7992

    Jerry,

    As this is a closed loop system it is hard to decompose where the sources of error are; some is likely related to the internal architecture of the AD598 and some is related to the choice of external components and the sensor. My comment only reflected…

  • AD7992-0

    你好,关于AD7992有官方驱动程序参考嘛?另外,我想问一下,启动和停止时序图上比较清楚,ACK(应答信号)从时序图上不是很清楚,请问有详细的时序图嘛?AD7992-0供电电压为5V,最小转换时间为多少?

  • AD7992 Mode 3

    Hi,

    When AD7992 is operated in Mode 3 - Automatic cycle mode, what should be the connection for CONVSTn pin?

    thanks,

  • AD7992 driver not providing in_voltage_scale

    Hi,

    I'm using AD7992 on a custom board and its Linux driver seems to only partially work. I'm using linux kernel 4.9.4 and I've defined the device tree as follows:

     ad7992_vcc: fixedregulator0 {
        compatible = "regulator-fixed";
  • AD7992 Voltage Applied to CONVST and ALERT

    Hello,

    I'm using AD7992 and I have VDD set to 5.0V but my MCU is at 3.3V. There is a condition where 5.0V gets turned off to save power, but the CONVSTn and ALERT/BUSY lines are pulled up to 3.3V with a pull-up resistor in order to communicate with the…

  • AD7992 I2C reads same channel twice

    Hi

    We are using both input channels of the AD7992 and its power supply is the reference. We use the command mode (mode 2), to set the ADC up and read the data back it. The I2C sequence used is as explained in the datasheet:

    <7-bit address + W> ACK …

  • AD7992 - Cannot see device on I2C-Bus

    Dear community,

    I am facing a problem when trying to use the AD7992. I have a Linux based Board which I am using for development of different sensor systems. The board has been extended by using a PCA9544A Multiplexer (4-Channel) to have 4 I2C-Busses…

  • AD7992: Blocking conversion or register update in Modes 2 and 3

    I would like to be able to "freeze" the value in the conversion register while in Mode 2 using a signal local to the AD7992.  Will holding ^CONVST high prevent the start of conversion that would be initiated by an I2C write command (or at least…

  • Is I2C Clock required in AD7992 Automatic Cycle Conversion mode?

    Hi All,

    We are using AD7992 analog to digital converter in our new

     

    DWDM-PON based ONT design. The preferred mode of operation for the

     

    converter is Mode 3 i.e. the Automatic cycle mode. Please confirm

     

    whether the I2C clock is used for polling…

  • AD7992-0驱动代码问题紧急求救

    你好,最近在用AD7992,驱动是参考AD7991代码的,但是我看AD7991驱动的时候,有个delay(1000);这个代码延时大概是多长,我按照时序图写的代码不知道为什么一直读取出来的数据是FF,希望能得到官方支持。谢谢,希望尽快回复。
