Power Supply Considerations in iCoupler^®Isolation Products

by Rich Ghiorse

INTRODUCTION

This application note is a guide to help users understand the

function of Analog Devices iCouplers under various power

supply conditions. Also discussed are the details of calculating

supply current consumption and power dissipation.

channel consists of CMOS input and output circuits and a chip-

scale transformer (Figure 1). In all applications, an iCoupler is

ground. Various scenarios must be considered during design to

ensure that all powered states are understood.

iCoupler products offer an alternative isolation solution to

optocouplers with superior integration, performance, and

power consumption characteristics. An iCoupler isolation
