ADN4622BRNZ-RL

Overview

The ADN4622BRNZ-RL is a quad-channel digital isolator manufactured by Analog Devices Inc., designed for high-speed data transmission. It features a 2+2 channel configuration supporting LVDS signals at data rates up to 2.5 Gb/s, providing a total bandwidth of 10 Gbps across all channels. The device operates with supply voltages ranging from 1.7 V to 1.9 V and 3 V to 3.6 V, consuming typical operating currents between 95 mA and 140 mA depending on the specific voltage rail. It offers a typical propagation delay of 2.15 ns with rise and fall times of 180 ps. The isolator provides an insulation voltage of 5700 Vrms and complies with TIA/EIA-644-A LVDS signal levels. It is housed in a 28-lead wide-body SOIC package (SOIC_W_FP) with finer pitch, ensuring 8.3 mm creepage and clearance distances.

Feature Summary

• Provides robust galvanic isolation between circuits using capacitive coupling technology.
