LW3720 Passive 4¨C20 mA Signal Isolator, 2 Inputs 2 Outputs

The LW3720 is a 2-channel passive 4¨C20 mA signal isolator that operates without an external power supply. Each channel isolates a 4¨C20 mA signal between the input and output circuits, helping eliminate ground-related interference and improve signal transmission reliability.
