ADUM2211TRWZ-RL

Overview

The ADUM2211TRWZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology for signal transmission. It operates on a single 5 V supply with low power consumption of 1.6 mA per channel at data rates up to 1 Mbps and 3.7 mA at higher speeds. The device provides 5000 Vrms isolation voltage and supports bidirectional communication. Key electrical parameters include a maximum data rate of 10 Mb/s, propagation delay of 50 ns, and common-mode transient immunity of 25 kV/µs. It functions within an operating temperature range of -40°C to +105°C and is housed in a 16-pin SOIC-W package.

Feature Summary
