GENERAL DESCRIPTION

The ADuM6400/ADuM6401/ADuM6402/ADuM6403/ADuM64041 are quad-channel digital isolators with isoPower?, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler? technology, the dc-to-dc converter provides up to 400 mW of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the power levels shown in Table 1. These devices eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs.
