ADM3095EBRZ

The ADM3095EBRZ is a 3.0 V to 5.5 V, 2.5 Mbps, RS-485 transceiverthat features up to ±42 V ac/dc peak bus overvoltage faultprotection on the RS-485 bus pins. This device is designed towithstand overvoltage faults, such as short circuits directly to powersupplies, and overvoltage faults, such as ±24 V ac suppliesconnected in error to the RS-485 A and B bus pins. TheADM3095EBRZ is an RS-485 transceiver that integrates IEC 61000-4-5Level 4 surge protection, allowing up to ±4 kV protection onthe RS-485 bus pins. The device has IEC 61000-4-4 Level 4electrical fast transient (EFT) protection up to ±2 kV, andIEC 61000-4-2 Level 4 electrostatic discharge (ESD) protectionon the bus pins, allowing the device to withstand up to ±15 kVon the transceiver interface pins without latch-up or damage.

This device has an extended common-mode input voltage rangeof ±25 V to improve data communication reliability in noisyenvironments over long cable lengths where ground loop voltagesare possible. The combination of extended common-mode inputvoltage range, overvoltage fault protection, surge protection, EFTprotection, and ESD protection make the ADM3095EBRZ acompletely integrated electromagnetic compatibility (EMC)protected RS-485 transceiver.

The ADM3095EBRZ also features a logic supply pin, VIO, for a flexibledigital interface, operational to voltages as low as 1.62 V. TheADM3095EBRZ is PROFIBUS® compliant with a high driverdifferential output voltage, VOD, of 2.1 V minimum at power supplyvoltages greater than 4.5 V. The device is fully characterized overextended operating temperature ranges, with options of −40°C to+125°C, and is available in a 16-lead, narrow body SOIC package..
