MAX22441CAEE+

MAX22441CAEE+ is a 4-channel, reinforced, ultra-low-power digital galvanic isolator using Analog Devices proprietary process technology. This device transfers digital signals between circuits with different power domains, using as little as 77.04µW per channel at 1Mbps (1.8V supply). The ultra-low-power feature reduces system dissipation, increases reliability, and enables compact designs. Devices are available with a maximum data rate of 10Mbps and with default-high or default-low outputs. The devices feature 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, compact micro PLC, battery management, parasitically powered applications.
