Hi

I'm using ADuM1441 in my design. Out of many boards manufactured only in one board when input logic is zero output logic goes to high only on some power On. Very often this happens in some power ON. What is the reason for this unknown behaviour. Can…

Hello

I'm using ADuM1441 in my design. From main power supply turning On time VDD2(output) power has delay of 500us. But VDD1(input) power takes around 2.6ms from main power supply turn on.

So ADuM1441 gets it's output power first compared input power…

Hi,

As per CN-0382 Circuit note AD7124 SPI communication input pins CS, SCLK & DIN are connected to Adum1441 logic input points VIA,VIB & VIC and  SPI communication output pins DOUT connected to Adum1441 logic output point VOD.

But CN-0376  Circuit…

Hi,

I am puzzled.

Fig 1 of the datasheet suggest there are 2 bi-directional channels and two one-way channels.

Table 23 shows 4 on-way channels; 3 from left to right, 1 from right to left.

Which ones are bidirectional, which ones are uni directional?

Hi,

we have chosen AD7124-4 A/D chip for four channel Analog input (4 to 20mA) application and chosen ADuM1441ARQZ SPI Isolator for isolating MCU.

ADuM1441ARQZ chip have 16pin with enable feature. But our application enable feature not require, So I can…

Hi

I'm using ADuM1441 in my design.  I'm using SPI interface in my design which passes through ADuM1441 digital isolator. 

It passes mosi clock and chip select properly from mcu to slave.  I have connected miso to vid of ADuM1441(slave side) and…
