The ADM2561EBRNZ-RL7 is a 3 kV RMS signal and power isolated RS-422/RS-485 transceiver from Analog Devices / Maxim Integrated. It supports data rates up to 500 kbps and offers full and half duplex operation with 2/2 driver/receiver configuration. The device features an integrated isolated DC-to-DC converter and passes EN 55032 Class B radiated emissions on a 2-layer PCB.
Key electrical specifications include a wide supply voltage range of 3 V to 5.5 V for VCC and 1.7 V to 5.5 V for logic VIO, allowing flexible interface with various logic levels. The receiver provides 25 mV hysteresis and supports up to 192 bus nodes due to its 72 kΩ input impedance. Enhanced ESD protection on the RS-485 bus pins includes ±12 kV contact discharge and ±15 kV air discharge per IEC 61000-4-2. The device also offers high common-mode transient immunity of 250 kV/µs.
The transceiver is housed in a 28-lead BSSOP package (0.295" width, 7.50 mm) with surface mount mounting, specifically the 28-SOIC-W-FP supplier device package. It operates over a wide temperature range of -40°C to 105°C, making it suitable for industrial environments. The device includes features such as cable invert smart feature for correcting reversed connections, full hot swap support, and receiver fail-safe for short-circuit, open-circuit, and floating inputs.
The supply voltage range is 3 V to 5.5 V.
The data rate is 500 kbps.
The isolation voltage is 3 kV rms.
The operating temperature range is -40°C to 105°C.
The package is 28-BSSOP (0.295", 7.50mm Width) with supplier device package 28-SOIC-W-FP.
ESD protection on RS-485 bus pins: ≥±12 kV contact discharge and ≥±15 kV air discharge per IEC 61000-4-2.
RoHS3 Compliant (unverified status).
