Hi Terumasa,

   I just had it confirmed, the watchdog is normally found on standard digital isolators but not on the AD7401A. Regarding the next question, when VDD1 is off, this means something happen on the hot side, the cold side(secondary) will retain…

Hi Jatin,

The AD7400A and the AD7401A parts are our parts that are targeted at shunt current monitor applications.

They accept signals in the +/-250mV range and have in-built isolation based on ADIs iCoupler technology.

The output of the AD7400A and…

FMCMOTCON1 provides electrical isolation between the FPGA and the power stage.

The components used to provide electrical isolation are:

     - ADuM7640 for digital signals

     - AD7401A for analog signals

     - ADuM500 for power supplies

Hi Johnny ,

Thxs a lot.  I am tring to develop a simple Bus functional model for AD7401A in order to test my design . I have few silly doubts could you please clarify me .

From the Page 1 of AD7401A data sheet there is a functional block diagram.

ADSP-CM40x提供 全sinc滤波器，可实现与隔离式Σ-Δ调制器(AD7400A / AD7401A) 的直接接口，可用于分流检测系统架构中。

JMGL: Looking at the your description of your application, I think it is important that the resistor divider you use has a high resistance so that it does not consume too much power and cause drift in resistance value.  In the response from Nicola to use…

Hi Natanel,

The internal clock on the AD7400 and AD7400A is used to clock the converter internally and also to allow the user to clock out the data bits from the modulator into an FPGA for example or other receiving device.

This clock typically runs…
