Working Principles

The OP90GS is an operational amplifier (Op-Amp) that amplifies and conditions input signals. It operates based on the principles of differential amplification, where the difference between the non-inverting and inverting input voltages is amplified by a high gain factor. The amplified output signal is then available at the OUT pin.

Detailed Application Field Plans

The OP90GS is commonly used in various applications, including:

1. Audio Amplification: Provides low noise amplification for audio signals in audio equipment such as amplifiers and mixers.
2. Sensor Signal Conditioning: Amplifies and conditions weak sensor signals for accurate measurement in industrial control systems.
3. Instrumentation Systems: Used in precision measurement instruments to amplify and condition signals from sensors or transducers.
4. Active Filters: Enables the design of active filters with specific frequency response characteristics.
5. Data Acquisition Systems: Used in data acquisition systems to amplify and condition analog signals before digitization.
