MAX22290CASA+

MAX22290CASA+ is a reinforced, fast, low-power, two-channel digital isolator. It uses Analog Devices’ proprietary process technology. The device transfers digital signals between circuits with different power domains, using as little as 0.78mW per channel at 1Mbps (1.8V supply). The low-power feature reduces system dissipation, increases reliability, and enables compact designs. It features low propagation delay and low clock jitter, which reduces system latency. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators. The device features two channels transferring data the same direction. Key applications include industrial: isolated SPI, isolated RS-232, RS-485/RS-422, CAN, fieldbus communications, motor drive.
