Overview
The ADN4624BCPZ, produced by Analog Devices Inc., is a high-speed differential signal isolator designed for applications requiring galvanic isolation of low voltage differential signaling (LVDS) signals. This quad-channel device operates at data rates up to 2.5 Gbps, making it suitable for high-speed data transmission and isolation. The ADN4624BCPZ integrates Analog Devices' iCoupler technology, which enhances high-speed operation and provides drop-in galvanic isolation of LVDS signal chains.
