• AD5754

    最近正在调试AD5754,芯片电压正常,±12,3.3v,和2.5v都正常供入。但是用FPGA写驱动程序是发现,只能读,SDO信号数据位全为0。不能够写入寄存器。下面附上我的波形

    My initial write on the AD5754 is ignored ?

  • RE: Output Variation of HMC733

    BTW, the sweeping signal is just controlled by the tuning voltage which is generated by AD5754.

  • AD5754 - no output

    Hi!

    I'm using AD5754 DAC with STM32 MCU (3.3v).

    Output of DAC loaded to 5 kOhm / 200 Ohm resistor divider, Vdd is 5v, AVdd and Avss is +12 and -12 volts, reference is 2.5v. LDAC, CLR and BIN2COM are tied to 5v.

    I can program DAC (0x0c0004, 0x10000e…

  • RE: AD5754R和STM32通过SPI通讯无输出问题

    你看AD5754的14号管脚,datasheet上是要接数字电源正,我总觉得这里是不是应该和ADuM1410的16号管脚是同一个电源正。

    AD5754输入的信号的高电位有5V。

  • hi,am interfacing with AD5754.i am not getting about clear and load command .what is the value for clear and load in control register.

  • RE: AD5754 clear issue

    Hi,

    I have tested this with the evaluation board in our laboratory. To answer your questions:

    1. Can I set control register when I let Clear low?

         A: You can change the CLRSEL register when CLEAR pin is low but it will have no effect to the DAC. The…

  • RE: AD5754 Exposed Paddle

    Hi,

    The substrate of the AD5754 needs to remain reverse biased with respect to all the N-wells sitting in the substrate. To do this, the substrate should be maintained at the lowest potential which is AVSS. If this is the case there will be no diodes…

  • RE: 这样使用AD5757和AD5754的用法是否正确

    AD5757基本正确。

    AD5754不需要在输出端链接2Kohm的电阻和4nF的电容.
