MAX22820EAWA+

MAX22820EAWA+ is a 2-channel, reinforced, ultra-low-power digital galvanic isolator using Analog Devices’ proprietary process technology. It features reinforced isolation with a withstand voltage rating of 3KVRMS for 60 seconds. This device transfers digital signals between circuits with different power domains, using as little as 90.7μW per channel at 1Mbps (1.8V supply). The ultra-low power feature reduces system dissipation, increases reliability, and enables compact designs. The device features low propagation delay and low clock jitter, which reduces system latency. Independent 1.71V to 5.5V supplies on each side also make the devices suitable for use as level translators. It is used in applications such as 4-20mA loop process control, battery management, compact micro PLC, and parasitically powered applications.
