Working Principles

The ADUM3190TRQZ utilizes a proprietary iCoupler® technology, which combines high-speed CMOS and monolithic air core transformer technologies. This technology enables the transfer of digital signals across an isolation barrier without the need for physical connections.

The device consists of two separate integrated circuits, each containing a digital isolator. These isolators use the iCoupler technology to transmit digital signals across the isolation barrier. The input signals are converted into a differential signal, which is then transmitted through the isolation barrier using the integrated transformer. On the receiving side, the differential signal is converted back into a digital output.

The isolation barrier provides galvanic isolation, protecting the connected circuits from voltage spikes, ground loops, and other electrical disturbances. This ensures reliable and safe communication between the isolated circuits.

Detailed Application Field Plans

The ADUM3190TRQZ is widely used in various applications that require high-speed digital signal isolation. Some common application fields include:

1. Industrial Automation: Isolation of control signals in PLCs (Programmable Logic Controllers), motor drives, and industrial communication systems.
2. Medical Equipment: Isolation of sensitive digital signals in patient monitoring devices, medical imaging systems, and diagnostic equipment.
3. Power Electronics: Isolation of digital control signals in power inverters, motor drives, and renewable energy systems.
4. Automotive Electronics: Isolation of digital signals in automotive control modules, battery management systems, and electric vehicle charging stations.
5. Telecommunications: Isolation of digital signals in communication interfaces, network equipment, and data transmission systems.
