• ADP1706 SSpin Unconnect


    I am considering ADP1706.

    I can start softly by attaching a capacitor to the SS pin,
    What will happen if no capacitor is attached to the SS pin?

    Will it be a soft start of about 48us like ADP1707 / 1708?

    Best Regards


  • RE: ADP1706 Recommended Thermal VIA and Stencil

    Hi Yuki,

    Apologies for the delay.

    1. For thermal vias, we recommend using JESD51-5 (under Section 4) guide which is having 0.3mm diameter. You could have 4 vias for this part's EPAD.

    2. You can refer to the image below for dimensions:

    您好。ADIS16334,ADIS16364, ADIS16445零偏稳定性、温度校准范围、温漂等也有不同。详细区别请参考产品数据手册。传感器抗磁场干扰能力比较好,使用控制器通过SPI接口和传感器通信就可以使用。您可以参考ADIS16445,ADIS16485.电源可以参考ADP1706/1707/1708

  • RE: Recommended 1.8V regulator for 8 DDS chips

    Hi Prakash BJ,

    The AVDD and DVDD supply pins of the AD9959 draws a maximum of 325mA when all channels are turned on.

    The 800mA maximum output current of the ADM7160 can only supply up to two DDS chips.

    There are higher current output LDOs such as the…

  • RE: AD9266 digital output level

    Hi Jacques,

    Thanks for trying the drive strength adjustment. I should have mentioned this earlier; the different fields in Register 0x15 are enabled/disabled by Bit[7] in Register 0x14. For example, the default value of Register 0x14[7:0] = 0x00, which…

    Hi Tom

    Many thanks for this.

    After a lot of wire mods, I got the AD9125 eval board working with the tester. I am able to read and write to the device and get a signal on the DAC outputs using the NCO. I tried the Parallel port, but this was unsucessfull…
