Overview
The ADN4624BCPZ-RL, produced by Analog Devices Inc., is a high-speed, quad-channel, signal isolated Low Voltage Differential Signaling (LVDS) buffer. This device is designed to operate at data rates up to 2.5 Gbps, making it suitable for high-speed applications requiring galvanic isolation. The ADN4624 integrates Analog Devices' iCoupler® technology, which enhances high-speed operation and provides drop-in galvanic isolation of LVDS signal chains. It is fully specified over a wide industrial temperature range and is available in various package options, including a 28-lead SOIC_W_FP and a 6 mm × 6 mm LFCSP package.
