ADuM7643 - Analog Devices

ADuM7643 1 kV RMS Six-Channel Digital Isolators

The ADuM7640/ADuM7641/ADuM7642/ADuM76431 are 6-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. These 1 kV digital isolation devices are packaged in a small 20-lead QSOP. They offer space savings and a lower price than 2.5 kV or 5 kV isolation solutions when only functional isolation is needed. This family, like many Analog .
