Product Summary
The ADUM7441CRQZ is a 4-channel digital isolator based on the iCoupler technology. The ADUM7441CRQZ quad 1 kV digital isolation device is packaged in a small 16-lead QSOP. While most 4-channel isolators come in 16-lead wide SOIC packages, the ADUM7441CRQZ 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 ADUM7441CRQZ offers a lower price than 2.5 kV or 5 kV isolators where only functional isolation is needed. Applications of the ADUM7441CRQZ are: General-purpose, multichannel isolation, SPI interface/data converter isolation, RS-232/RS-422/RS-485 transceivers, Industrial field bus isolation.
