Additional Details

The ADUM485EARZ typically includes features such as short-circuit protection and over-temperature protection to enhance reliability. Key specifications include the isolation voltage (e.g., 2.5 kV rms), data rate (e.g., 1 Mbps), power consumption (e.g., 2.5 mA per channel), and propagation delay (e.g., 25 ns). It is commonly available in a narrow-body SOIC (Small Outline Integrated Circuit) package for space-saving designs. The isolator does not require external drivers.

Its isolation properties make this part perfect for protecting sensitive control circuits for industrial equipment and power supplies.
