Overview
The ADUM6401CRIZ is a quad-channel digital isolator produced by Analog Devices Inc., incorporating the company's proprietary iCoupler® technology. This device features an integrated, isolated DC-to-DC converter known as isoPower®, which provides up to 400 mW of regulated, isolated power at either 5.0 V or 3.3 V. This integration eliminates the need for a separate isolated DC-to-DC converter in low-power, isolated designs. The ADUM6401CRIZ is packaged in a 16-lead SOIC wide body package, offering high temperature operation up to 105°C and high common-mode transient immunity of more than 25 kV/μs.
