The ADI ADuM144x digital isolators also offer a low power. 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.
EVAL-ADuM144x-EBZ supports the ADuM144x family of ultra low power, quad channel isolators. It provides a JEDEC standard QSOP16 pad layout, support for signal distribution, loop back, bypass capacitors, and loads referenced to VDDX or GNDX.
