Working Principles

The ADUM4190ARIZ is an isolation amplifier that utilizes a combination of optical and magnetic isolation techniques. The input signal is converted into an optical signal, which is then transmitted across the isolation barrier. On the output side, the optical signal is converted back into an electrical signal. This ensures complete galvanic isolation between the input and output circuits, protecting sensitive components from high voltage transients and reducing noise interference.

Detailed Application Field Plans

• Industrial automation: Isolation of control signals in motor drives, power supplies, and PLCs.
• Medical equipment: Isolation of patient monitoring signals to ensure safety and prevent ground loops.
• Power grid monitoring: Isolation of measurement signals in smart meters and energy monitoring systems.
• Automotive electronics: Isolation of sensor signals in electric vehicles and hybrid cars.
