Analog Devices Inc. Presents: The OP491 Precision Micropower Quad Operational Amplifier

The OP491 is a high-performance, quad operational amplifier brought to you by Analog Devices Inc., a leader in precision signal processing technology. This device boasts a unique combination of low power consumption and high precision, making it an ideal choice for battery-powered applications and instrumentation.

With a supply voltage range of 3V to 30V (±1.5V to ±15V), the OP491 ensures versatile application across various power environments. Its micropower operation, drawing a mere 25 μA of quiescent current per amplifier, significantly extends the life of battery-operated devices without sacrificing performance.

The OP491 features a tight offset voltage of 1 mV and a low input bias current of 1 nA, which are crucial for accurate signal amplification in precision measurement equipment. Additionally, its high open-loop gain of 500,000 V/mV ensures that the output is a true representation of the input, even with high source impedances.

Furthermore, the OP491 is unity-gain stable, which allows for use in various feedback configurations without the risk of oscillation. Its large output swing, close to the supply rails, maximizes the dynamic range in single-supply applications. This feature is particularly beneficial in analog-to-digital converter (ADC) driving circuits, where maximizing the input range without clipping is essential.

Whether you're designing portable medical devices, sensor interfaces, or any other system requiring high precision and low power, the OP491 from Analog Devices Inc. is an excellent choice. Its robust feature set ensures that it can meet the stringent requirements of the most demanding applications.

Choose the OP491 for your next design project and experience the perfect balance of power efficiency and precision in a compact, quad operational amplifier package.
