I have an existing RS485 half duplex design using the ADUM3402, the ADM3078 running at 3.3V and a DC-DC convertor. I'm looking to save some space (as always) and am considering using the ADM2682. However, I've been trying to interpret the supply current…
Hello,
The customer would like to get advice about hot-swap ADM3078E.
ADM3078E has thee mode (shut-down, rx, tx).
Do you have any particular recommended mode when ADM3078E face hot-swap?
Thank you for your help as always.
Best regards,
Sofy
Hello,
I am currently working on a design that includes a RS485 network. Currently there is a PC with PCI based RS485 transceiver card and I am designing a circuit that will be reporting data to that PC. The RS485 node that I am designing will never…
Hi
RS485 receiver should operate by +/- 200mV differential signal.
ADM3078E receiver spec defined the delay time by +/- 1V input.
Could you show us the propagation delay at +/- 200mV input?
How about input amplitude dependency?
Regards

Hi Clark,
The ADM485E is specified for a Vcc supply of 4.5-5.5V. Is there any reason why your design cannot meet this specified range?
We have a wide range of half duplex RS-485 transceivers that can operate at 3.3V supply ranges, For example the ADM3065E…
Hi Akhil,
Just an extra note -- ADI also has a range of more ESD robust RS-485 transceivers at 3V and 5V operation:
5 V operation:
ADM485E, ADM487E, ADM1487E have 15 kV HBM ESD protection
3 V operation:
ADM3070E - ADM3078E have 15 kV HBM ESD pro…
Excellent point!
If you have a 4V VOD on a 5V transceiver, for example, & there's an external resistor biasing network on the other side to 3.3V, this could present a current path into the supply. This path would need to be blocked alright. But…
