The ADUM1250ARZ-RL7 from Analog Devices is a general-purpose digital isolator in the ADUM1250 series with 2 bidirectional channels and 1 input line. A digital isolator carries logic signals across an insulating barrier so that the two sides can sit at different ground potentials without a conductive path between them. The ADUM1250ARZ-RL7 supports a 1Mbps data rate with a 150ns propagation delay and 85ns pulse width distortion, operates at 5V across a 3V to 5.5V range at 5mA supply current, and does not provide isolated power. It is supplied in an 8-pin SOIC N surface-mount package, rated for -40°C to 105°C, RoHS compliant, in tape and reel at 1, 000 per package.

Bidirectional two-channel isolators are commonly used to isolate open-drain two-wire buses, keeping a controller separated from sensors, power modules, or field wiring that reference a different ground. Isolation of this kind is standard practice in industrial equipment exposed to long cable runs and ground potential differences, in medical devices requiring patient-side separation, and in power conversion and battery management systems where the control side must not share a ground with the high-voltage side. The 1Mbps rate covers control and telemetry links rather than high-speed data. Buyers are typically industrial automation, medical device, and power electronics OEMs.
