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
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…
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…
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?

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…
