µModule Isolated Transceivers
Analog Devices µModule (micromodule) isolated transceivers provide robust galvanic isolation for digital serial communication interfaces, including SPI, I2C, RS-485/RS-422, RS-232, and USB. Isolation barriers are implemented using Ethernet transformers, coupling capacitors, or embedded inductors. All devices are simple to configure, have very low EMI susceptibility and emissions, and feature high noise immunity to preserve signal integrity.
Our µModule® (power module) technology helps reliably integrate inductive/magnetic isolation, discrete components, ICs, and power onto a single substrate PCB. Any application, from signaling to sampling, can be supported by the platform. Our technology achieves isolation up to 3500 V rms, and is consistently rugged and reliable.
