Based on the iCoupler^® and isoPower^® chip scale transformer technology, the ADM3260 is a hot swappable digital and power isolator with two nonlatching, bidirectional communication channels, supporting a complete isolated I²C interface, and an integrated isolated dc-to-dc converter, supporting up to 150 mW of isolated power conversion.

iCoupler is a chip scale transformer technology with functional, performance, size, and power consumption advantages as compared to optocouplers. The bidirectional I²C channels eliminate the need for splitting I²C signals into separate transmit and receive signals for use with standalone optocouplers.

Based on the Analog Devices, Inc., isoPower technology, the on-chip isolated dc-to-dc converter provides a regulated, isolated voltage of 3.15 V to 5.25 V with up to 150 mW of output power.

With the ADM3260, the iCoupler and isoPower channels, along with the I²C transceivers, can be integrated with semiconductor circuitry, which enables a complete isolated I²C interface and allows the power converter to be implemented in a small form factor. The ADM3260 is available in 20-lead SSOP package and has an operating temperature range of −40°C to+105°C.

isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations
