Part Number: TMP422
Other Parts Discussed in Thread: TMP461, , DXP, TMP464, TMP468

Hi,

We commonly use the TMP461 to interface with devices which only have DXP pulled out. In that case, we would connect DXN to GND. Can the TMP422 support this mode? We can’t tell in reading through the datasheet.

Thanks,

David

Hi David,

Yes, you can connect TMP422 diode pins to ground. DX1/DX2 make up one pair of diode pins, so the one that isn't used as DXP should be connected to ground.

Have you considered TMP464 or TMP468?

Thanks,
Ren
