**OP90GSZ-REEL: A Comprehensive Technical Overview of this Precision Operational Amplifier**

The **OP90GSZ-REEL** represents a pinnacle of precision analog design, offering engineers a unique combination of ultra-low power consumption and high accuracy. This operational amplifier from Analog Devices is packaged in a space-saving SOIC-8 format and supplied on a reel for high-volume manufacturing, making it a preferred choice for battery-powered and portable instrumentation.

A defining characteristic of the OP90 is its remarkable **ultra-low supply current of just 20 µA maximum**. This feature is paramount for applications where power efficiency is critical, enabling extended battery life without compromising performance. Despite this minimal power draw, the OP90 does not sacrifice accuracy. It boasts an **impressive low input offset voltage of 150 µV** and an exceptionally low input offset voltage drift, ensuring precise signal conditioning over a wide temperature range.

The amplifier operates on a single-supply voltage as low as **+1.6 V to +36 V**, or on dual supplies up to ±18 V. This wide operating range provides exceptional design flexibility, allowing the same part to be used in both 3.3V modern microcontrollers and older ±15V industrial systems. Furthermore, the OP90 features **rail-to-rail output swing**, maximizing the dynamic range of the signal, especially critical in low-voltage single-supply applications.

The device also includes **internal RFI/EMI rejection filters**, which enhance its resilience in electrically noisy environments. This makes it exceptionally robust for use in industrial control systems, medical equipment, and automotive sensors where electromagnetic interference is a common challenge.

**ICGOOODFIND**: The OP90GSZ-REEL stands out as an exceptional solution for designers who refuse to choose between precision and power efficiency. Its blend of micro-power operation, high accuracy, wide voltage range, and built-in noise protection makes it an indispensable component for modern, portable, and sensitive electronic equipment.
