In my application I am using ADXL345 Accelerometer. The Microprocessor used is C8051F120.
At beginning of the project I used the ADXL345 directly connected to the micro (without isolation) and the accelerometer work perfectly.
I have added some…
I use ADuM2401 for the isolation between the meter IC (Cirrus 5490 ; before the bridge diode) and secondary side MCU.
I found out that the Vdd1 (Secondary side) will pull down the 3.3V and cause the MCU shunt-down during the surge test (4KV, from…
We don't have the maximum rise/fall time data for ADuM2401.
The IEC 60747-5-2 standard applies only to optocoupler devices. There is a similar standard for non-optical isolators maintained by VDE in Germany called VDE V 0884-10. This standard provides a reinforced safety rating based on rigorous…
I am using ADuM2401 to interface with other external digital equipment. What will happen if my system is powered down while the external equipment is still turned on? There will in this case be 5V on the input pins on my ADuM2401 which may power…
is it possible to get a higer isolation voltage by using iCouplers in serial?
e.g. ADuM6401 and ADuM2401? to get an iso voltage of 8kV?
I would like to ask if any test result report for Radiated Emission is available for ADI iCoupler, especially for ADuM2401 and ADuM4401?
