ADM211EAR Description

Short technical summary and product information.

The ADM211EAR from Analog Devices is a rugged RS-232 transceiver designed for operation in harsh electrical environments. It is part of the ADM2xxE family that complies with the EU EMC directive 89/336/EEC, offering high levels of immunity and low emissions. The device provides four drivers and five receivers, supporting full duplex communication over an RS-232 interface with a guaranteed data rate of 230 kbps.

 

Electrical specifications include a single 5 V power supply with an operating range of 4.5 V to 5.5 V. The transceiver features robust ESD protection: ±15 kV human body model, ±8 kV IEC 1000-4-2 contact discharge, and ±15 kV air-gap discharge. Additional protection includes fast transient burst immunity (IEC 1000-4-4). The receiver hysteresis is 650 mV, and the shutdown mode reduces power consumption to just 1 µW.

 

The ADM211EAR is housed in a 28-pin SOIC package with a width of 7.50 mm, suitable for surface-mount assembly. It operates over the industrial temperature range of -40°C to +85°C. This transceiver is ideal for applications in laptop computers, notebooks, printers, peripherals, and modems where reliable RS-232 communication is required under demanding conditions.
