CMT8120W0 HopeRF Micro electronics isolator offering high data rate and signal isolation for industrial
Product Overview
The CMT812X is a high-performance, dual-channel digital isolator utilizing silicon dioxide (SiO2) insulation technology, capable of supporting up to 5 kVrms isolation voltage. It facilitates communication between two different power domains, preventing noise currents from affecting sensitive local ground or circuits. Available in CMT812X1 (default high output) and CMT812X0 (default low output) variants, this isolator offers superior electromagnetic compatibility (EMC) with low power consumption and low radiation, meeting system-level ESD, EFT, surge, and radiation compliance requirements. It is offered in SOIC-16 wide body, SOW8L wide body, and SOIC-8 narrow body packages.
