• AD5422: What is the role of R27 Socket in AD5422's EVB?

    Would you please help explain the role of R27 Socket in AD5422's EVB?

     

    This is an optional resistor that can be inserted to over-range the output,
    this resistor is placed in parallel with the internal resistor R3, this has the
  • ad5422 비정상 동작

    hello

    The AD5422 is in use and the part is acting abnormally.

    It works normally at first, but then suddenly breaks down.

    I set the setting to output ±10V, but 11.5V is output and

    Negative voltage is not output. Please refer to the table

  • Configuring AD5422 Midscale Voltage output

    Hi Team,

    I am able to get 0-5V output range with AD5422 DAC, but I want to set the output range in the Midscale range (between 0.5-5V).

    I tried to configure CLEAR SELECT and CLEAR bit in the AD5422 Control register but the lowest output value is always…

  • AD5422: HART compatability

    Would you tell if AD5420/2 are HART compatible now? Some customer will
    integrate HART in application. But now they only have AD421 to use. If we may
    also promote this part to meet HART compatible now?

     

    The AD5420 has passed the HART…
  • AD5422: 3 pin SPI interface

    Regarding AD5422:

    Why does its SPI interface not have a chip select pin?

    There is a LATCH pin but it doesn't make the system SPI compatible.

    Without a chip select pin it impossible to use a device on a SPI bus together
    with…
  • AD5422 - Connecting multiple DVCC outputs together

    I want to use multiple AD5422 IC's, all with DVCC SELECT pin unconnected (use of internal LDO).

    Is it possible to connect all DVCC outputs together to get more current for external circuitry?
    Or do I have to use diodes to decouple DVCC output?

  • AD5422 DAC SPI reference designs - Verilog

    Hi,

    We are using 16-Bit DAC AD5422 from Analog devices in one of our proof-of-concept designs. We need to communicate to the DAC over SPI interface. Could you please provide the reference design for AD5422 DAC SPI communication(Verilog).

    Thanks & Regards…

  • 关于AD5422的相关疑问

    工程师你好,最近正在选用4-20mA的输出DAC芯片,通过阅读AD5422的中文规格书(版本H),发掘了一些疑问,还望解答:

    1.AVDD输入范围是10.8V-40V,那么当接15V、24V、36V时,对芯片都会有什么影响呢?如此宽电压设计的用意是什么呢?

    2.我们项目中,要求输出0-5V模拟电压或是4-20mA的电流,因此您是建议AVSS依然接负压,还是可以接GND?如果接了GND,那么是否可以准确输出0V?

    3.5422是兼容SPI协议的,规格书图66推荐的是SPI菊花链的链接方式,但我认为菊花链方式无法让4pcs的5422同时接收SPI的MOSI信号…
