• AD5422供电问题

    1.AD5422选择4~20 mA、0~20 mA电流输出可以单电源供电吗?

    2.如果12V供电最大可带多少欧负载?

  • AD5422功耗问题

    AD5422在电流输出状态下最大功耗是多少W?参考设计PLC_Demo_System中的每块芯片都给了2W的电源模块,功耗有那么大吗?另外我在别人的一个设计中他用一个1w的电源模块给4片ad5244供电,也能正常工作,为啥

  • AD5422 max. update rate

    Hello all,

    I am wondering about the max. update rate for the AD5422.

    In the data sheet, I con find a lot of timings for the SPI-Interface.

    24 bits have to be transmitted to the DAC with up to 30MHz, and LATCH has to be low for min. 40ns.

    I can't find…

  • [AD5422] question about timing

    Hello

    I have 3 questions about AD5422.

    1. There is timing characteristics on the datasheet.

    As for t5 and t10, is this meaning we need 5us at least to write it into control register?

    2. During start-up, the customer format RESET and whiting control…

  • AD5422 SPI Communication

    Hi,

    I'm trying to send a simple 10V output command (in the 0-10V Range). Voltage output only 17mV and no changing.

    How can I fix this communication issue, any missing?

    Control Register:

    Msb

  • Dual DAC AD5422 Code

    Hi everyone,

    I have some questions for AD5422 , what is the importance of LATCH and CLEAR pins ? 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, i am not using daisy chain mode …

  • AD5422, confirming REFOUT specification

    Hi,

    AD5422 datasheet Rev.G page.12 Table 6. shows, [ Internal Reference Voltage Output. REFOUT = 5 V ± 2 mV ] for spec. of REFOUT.

    Against, same datasheet page.33 says [ an integrated 5 V voltage reference with initial accuracy of ±5 mV maximum ] at…

  • AD5422 minimum current load

        We have a design with the AD5422 operating in both current and voltage mode. Current and voltage terminals are not connected. Current mode is using external boost transistor.

    The voltage mode perfectly matches the specification, whereas we experience…
