Overview
The ADN4650BRSZ-RL7, produced by Analog Devices Inc., is a high-speed digital isolator that integrates low voltage differential signaling (LVDS) buffers. This device operates at data rates of up to 600 Mbps with very low jitter, making it suitable for applications requiring high-speed signal isolation. The ADN4650BRSZ-RL7 utilizes Analog Devices' iCoupler technology to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This technology allows for drop-in isolation of an LVDS signal chain, ensuring reliable and isolated high-speed data transmission. The device is available in a 20-lead shrink small outline package (SSOP) and is fully specified over a wide industrial temperature range of -40°C to +125°C.
