产品概览
The ADM2687EBRIZ-RL7 from Analog Devices is a fully integrated 5 kV rms signal and power isolated RS-485/RS-422 transceiver in a 16-lead wide-body SOIC package. It integrates iCoupler digital isolation, an RS-485 transceiver, and isoPower isolated DC-DC converter, requiring only a single 3.3V or 5V supply. Data rate is 500 kbps with ±15 kV ESD protection on bus pins.
