Analog Devices Inc. ADM3095E RS-485 Transceivers

Analog Devices Inc. ADM3095E Transceivers are completely integrated electromagnetic compatibility (EMC) protected RS-485 transceivers. The design combines overvoltage fault protection, surge protection, EFT protection, ESD protection, and an extended common-mode input voltage range. These 3V to 5.5V, 2.5Mbps, RS-485 transceivers offer up to ±42V AC/DC peak bus overvoltage fault protection on the RS-485 bus pins. In addition, the transceivers provide IEC 61000-4-4 Level 4 EFT protection up to ±2kV, and IEC 61000-4-2 Level 4 ESD protection on the bus pins. These protection features allow the ADM3095E devices to withstand up to ±15kV on the transceiver interface pins without latch-up or damage. Analog Devices ADM3095E RS-485 Transceivers have an extended common-mode input voltage range of ±25V. The extended common-mode input voltage range enables the ADM3095E to improve data communication reliability in noisy environments over long cable lengths with ground loop voltages.
