Overview
The ADUM3152BRSZ is a 7-channel digital isolator from Analog Devices Inc., optimized for isolated serial peripheral interfaces (SPIs). It utilizes Analog Devices' iCoupler® chip scale transformer technology, which ensures low propagation delay and high common-mode transient immunity. This component is designed to support SPI clock rates up to 17 MHz, making it suitable for high-speed applications. The ADUM3152BRSZ is packaged in a 20-lead SSOP package with a creepage distance of 5.1 mm, and it operates over a wide temperature range up to 125°C.
