Analog Devices ADuM144x Quad-Channel Digital Isolators

Analog Devices ADuM144x Quad-Channel Digital Isolators are micropower devices based on iCoupler® technology. ADI ADuM144x isolators combine high speed, CMOS, and monolithic air core transformer technologies to provide outstanding performance characteristics compared to optocoupler devices. These ADI digital isolators also offer the lowest power of any isolation device on the market. The ENX signals can be used to disable the internal refresh, which lowers the total quiescent current to less than 1µA. These devices free almost 70% of board space but can still withstand high isolation voltages and meet regulatory requirements. ADuM144x isolators operate with supplies as low as 2.25V. This device family also provides low, pulse width distortion <8ns. These devices also have an input glitch filter to protect against extraneous noise disturbances.
