ADUM1300

The ADuM1300 is a 3-channel digital isolator based on Analog Devices' iCoupler technology, offering superior performance compared to traditional optocouplers. It combines high-speed CMOS and monolithic transformer technology to provide reliable isolation without the design complexities associated with LEDs and photodiodes.

This isolator supports bidirectional communication and 3 V/5 V level translation, making it compatible with a wide range of systems. It features a high data rate of up to 90 Mbps (NRZ) and precise timing characteristics, including a maximum pulse width distortion of 2 ns and channel-to-channel matching of 2 ns. The device also boasts high common-mode transient immunity of greater than 25 kV/μs.

Designed for demanding applications, the ADUM1300 operates at high temperatures up to 105°C. It offers low power consumption, with maximum current draw per channel ranging from 0.8 mA at 3 V to 32 mA at 5 V, depending on the data rate. Safety and regulatory approvals include UL recognition for 2500 V rms for 1 minute and VDE certification.

The ADUM1300 is available in a 16-lead SOIC wide body package, with Pb-free models offered. Its applications include general-purpose multichannel isolation, SPI interface/data converter isolation, and RS-232/RS-422/RS-485 transceiver isolation, as well as industrial field bus isolation.
