The ADuM744x1 are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler devices and other integrated couplers. The ADuM744x family of quad 1 kV digital isolation devices is packaged in a small 16-lead QSOP. While most 4-channel isolators come in 16-lead wide SOIC packages, the ADuM744x frees almost 70% of board space and yet can still withstand high isolation voltage and meet regulatory requirements such as UL and CSA standards (pending). In addition to the space savings, the ADuM744x offers a lower price than 2.5 kV or 5 kV isolators where only functional isolation is needed. This family, like many Analog Devices isolators, offers very low power consumption, consuming one-tenth to one-sixth the power of comparable isolators at comparable data rates up to 25 Mbps. Despite the low power consumption, all models of the ADuM744x provide low pulse width distortion (< 5 ns for C grade). In addition, every model has an input glitch filter to protect against extraneous noise disturbances.
