**OP490GP: The High-Performance Optocoupler for Demanding Industrial Applications**

In the complex ecosystem of industrial automation, where high voltage transients, electromagnetic interference (EMI), and ground loops are constant threats, signal integrity is paramount. The **OP490GP stands out as a high-performance optocoupler** engineered specifically to meet these rigorous challenges, providing unparalleled reliability and noise immunity in harsh operating environments.

At its core, the OP490GP utilizes a **highly efficient GaAs (Gallium Arsenide) LED** coupled with an integrated photodetector. This advanced optical design is the foundation of its exceptional performance, enabling a **remarkably high Current Transfer Ratio (CTR)** with minimal deviation over time and temperature. This stability is critical for maintaining accurate signal transmission in long-running industrial processes, such as motor control and power inverter feedback loops, where even minor signal degradation can lead to system failures.

A key differentiator for the OP490GP is its **exceptional common-mode rejection (CMR)** capability. Industrial settings are rife with electrical noise from heavy machinery and high-power equipment. The OP490GP's ability to ignore these rapid common-mode voltage transients ensures that data signals are transmitted without corruption, safeguarding sensitive logic circuits from potentially damaging voltage spikes. Furthermore, it supports **high isolation voltage ratings**, typically up to 5000 Vrms, creating a robust safety barrier that protects low-voltage control systems from faults in the high-voltage primary side.

The device is designed for versatility and resilience. Its wide operating temperature range makes it suitable for applications from factory floor servo drives to outdoor renewable energy inverters. The combination of high speed, excellent noise immunity, and long-term reliability makes the OP490GP an indispensable component for designers who cannot compromise on system safety or performance.

**ICGOODFIND:** The OP490GP is a premium optocoupler solution that masterfully balances high-speed performance, superior noise immunity, and robust isolation. It is an optimal choice for engineers designing critical systems in industrial automation, motor drives, and power supplies where signal integrity and equipment protection are non-negotiable.
