• AD5144 Daisy-Chain Questions

    Hello!

    I am designing a circuit that wants 4 AD5144 chips to be daisy-chained together. The SPI bus that is interfaced with them is also shared with another chip that will be active when the ~SYNC pin on the digipots are pulled high (chip select disabled…

  • AD5144 I²C register addresses and read commands

    Hello,

    I'm trying to figure out how to read values from the registers via I²C on an AD5144. Unfortunately I am unable to find the required information in the datasheet and application notes. Can you please clarify the usage for me?

    Thanks in…

  • AD5144 SPI interface

    Hello,

    I'm trying to interface with AD5144 with SPI interface.

    When I try to perform reading from the EEPROM or RDAC or input register I do not get any result.

    Is there an elaborated timing diagram for the SPI interface?

    What is the sequence for reading…

  • How to read AD5144 eeprom for I2C

    SCHthis is my Schematic diagram。

    NOW,I can set RDAC through I2C,Timing in the picture。

    I want to know which Timing that to read eeprom form AD5144? thank you!

  • AD5144+LT3476使用问题

    AD5144+LT3476 搭配使用,发现LT3476的Vref只有0.8V,将两者断开后Vref=1.05V正常。AD5144的上电时序以及其他都已经符合SPEC要求,但是VREF接到AD5144的A端时还是会被拉到0.8V。请帮忙看看这是什么原因造成的。

  • 关于AD5144无法通过SPI读取和修改内部游标值

    STM32作为主控芯片发送读取、修改AD5144游标值的指令;而AD5144不返回相应游标值,而是返回STM32下发的指令。

    VDD端由5.45V模拟电压供电,Vlogic由3.3V数字电压供电。

    AD5144电路如图:

  • 如何通过IIC读取AD5144的RDAC寄存器的值

    ADI的工程师,您好,

    我使用的是ADSP21479与AD5144之间采用I2C方式通信。I2C通过gpio模拟。

    请问如何读取AD5144 RDAC寄存器的时序是怎样的,我在dadasheet中没有找到关于读寄存器的具体方法描述。如果有好的方法,请验证后回复,谢谢!

  • AD5144 Package dimensions from Rev B to Rev A datahseet

    Hi the person in charge,

    I helped to technical support in Japanese Auto market.

    When AD5144 datasheet change from Rev B to C, one value changes 0.25mm to 0.2mm. The customer wants to know background the change, so could you give your advice?

    One figure…
