• What is a baud rate of AD5700-1 to communicate with micro-controller

    I want to interface AD5700-1 with microcontroller. To interface it with controller, I require to know on how much baud rate AD5700-1 replies to the microcontroller.

  • AD5700/AD5700-1 Rx/Tx Pin Z in Power-down and Powered Off?

    Are the AD5700/AD5700-1 Rx and Tx pins in hi-z (essentially benign) when the part is powered-off and/or held in reset?

  • 急!!AD5700-1输出不正常求助

    参考CN0267画的电路图,AD5700始终不工作(怀疑是外部晶振的问题),后来换了AD5700-1,使用内部震荡且使能CLKOUT,但是示波器检测,CLKOUT无波形,AD5700-1的TXD引脚输入0X55,波形如下,但是HART_OUT引脚输出波形不对,如下图,这会是什么什么问题呢?备注:电路板默认配置使用AD5700的,使用AD5700-1时采用电路板割线和飞线进行的,不知道是否有干扰。

    图一、AD5700-1的TXD引脚输入0X55

    图二、AD5700-1的HART_OUT…

  • AD5700 and Bluetooth module

    Hi!

    I would like to make an ad5700-1 serial communication with the bluetooth module. The same communication with USB interface module occurred without problems.
    However, I realized that the bluetooth module does not generate the rts signal. Do you have…
