ADM2482EBRWZ

Overview

The ADM2482EBRWZ is a 3-channel digital isolator with an integrated RS-485 transceiver, utilizing iCoupler technology for galvanic isolation. It supports data rates up to 16 Mbps and operates on a single 3.0 V to 5.5 V supply. The device provides 2500 Vrms isolation voltage and 25 kV/µs common-mode transient immunity. Key electrical parameters include a maximum propagation delay of 100 ns, rise/fall times of 15 ns max, and a supply current of 6 mA. It dissipates 195 mW and functions within a temperature range of -40 °C to +85 °C in a 16-pin SOIC package.

Feature Summary

• Integrates a full/half-duplex RS-485 transceiver with a transformer driver for high-speed multipoint communication
• Provides galvanic isolation via iCoupler magnetic technology without optocoupler constraints
• Includes integrated ESD protection for robust signal integrity

Applications

• Industrial process controls
• Isolated RS-485 field buses
• Metering systems

Procurement Notes

Verify the specific suffix (e.g., REEL7) against the required packaging format, as tape-and-reel variants exist. Confirm RoHS compliance and lead-free status during sourcing. Ensure the selected variant matches the intended board assembly method, distinguishing between tube and reel packaging options available from distributors.

Selection Notes

Select this component when high-speed RS-485 communication requires galvanic isolation in a compact form factor. The integrated transformer driver eliminates external magnetics, simplifying design. Consider the 16 Mbps rate and 2500 Vrms isolation rating for applications demanding reliable noise rejection in electrically noisy industrial environments.
