ADM3095EBRZ

Single Transmitter/Receiver RS-485 16Pin SOIC N Tube

Product Details

The ADM3095E is a 3.0 V to 5.5 V, 2.5 Mbps, RS-485 transceiver that features up to ±42 V ac/dc peak bus overvoltage fault protection on the RS-485 bus pins. This device is designed to withstand overvoltage faults, such as short circuits directly to power supplies, and overvoltage faults, such as ±24 V ac supplies connected in error to the RS-485 A and B bus pins. The ADM3095E is an RS-485 transceiver that integrates IEC 61000-4-5 Level 4 surge protection, allowing up to ±4 kV protection on the RS-485 bus pins. The device has IEC 61000-4-4 Level 4 electrical fast transient EFT protection up to ±2 kV, and IEC 61000-4-2 Level 4 electrostatic discharge ESD protection on the bus pins, allowing the device to withstand up to ±15 kV on the transceiver interface pins without latch-up or damage.

This device has an extended common-mode input voltage range of ±25 V to improve data communication reliability in noisy environments over long cable lengths where ground loop voltages are possible. The combination of extended common-mode input voltage range, overvoltage fault protection, surge protection, EFT protection, and ESD protection make the ADM3095E a completely integrated electromagnetic compatibility EMC protected RS-485 transceiver.

The ADM3095E also features a logic supply pin, VIO, for a flexible digital interface, operational to voltages as low as 1.62 V. The ADM3095E is PROFIBUS® compliant with a high driver differential output voltage, VOD, of 2.1 V minimum at power supply voltages greater than 4.5 V. The device is fully characterized over extended operating temperature ranges, with options of −40°C to +125°C, and is available in a 16-lead, narrow body SOIC package..
