Overview
Description
ADuM1400ARW is a 4-channel digital isolator from Analog Devices (iCoupler technology). It provides galvanic isolation between a primary (input) side and a secondary (output) side, so signals cross the barrier without a direct ground connection. It’s used to isolate microcontrollers or logic signals from higher-voltage or noisy domains (industrial, automotive, sensor interfaces) while preserving fast digital signaling.
Key points:
- Four isolated data channels; supports common digital interfaces (SPI/I2C/UART-like signals).
- Independent VDD1 and VDD2 supplies (2.7–5.5 V typical).
- Very fast propagation delay and low power; designed for micr ocontroller-grade speeds.
- Reinforced isolation with ratings suitable for safety-critical applications (exact voltage rating depends on variant and package).
ARW denotes the specific package/lead finish variant (an 8-pin RoHS-compliant package). Check the datasheet for exact pinout, voltage ratings, temperature range, and isolation specs for your exact part revision.
