What DC-DC convertor are you using? Is it an isoPower solution, such as the ADuM5000?
The power conversion efficiency is not specified for the ADM2682E, it is restricted by the small size of the internal transformer and this is the reason…
At lower data rates, such as 10kbps or 20kbps it will be possible to communicate over much longer distances, up to 4000 feet.
Yes, correct, the termination resistor value should equal the characteristic impedance of the cable.
Yes, the 'inverse…
深圳 科技园 做数字电源 关注 数字隔离 ADM2485
We are manufacturer of range of actuators which uses RS485 communication as backbone.
Currently we are using TI, ISO3088 - isolated RS485 converter.
We are revisiting the design and want to have ADM2485 to be tried and if found satisfactory…
the RS-485 transceiver we used is ADM2485.
The power AC 220v is tied to node0, the node0 converts it to DC 12v, then the 12v is power for node1,2..N.
I hope the circuit I mentioned above can solve the prolbem.
The ADM2582E/87E is not profibus compliant. If a profibus compliant part is required, I would advise using the ADM2485. This part contains an integrated transformer driver that drives an external transformer which then gets rectified and regulated…
Have received a problem at use ADM2484E - the starting bit turns out with "step". The circuit drawing and signal photo in the appendix. In the photo:
- blue signal (3) - transmission enable - pin 5 DE ADM2484E
- green (2) - TxD signal on 6…
Yes, we do have RS-485 transceivers with integrated power isolation as well as signal isolation. The following parts all have isolated power using isoPower chip-scale micro-transformer technology:
