The OP490GSZ is a modern, high-performance, low-voltage operational amplifier, designed for industrial and instrumentation applications. The OP490GSZ is characterized by low input offset voltage and low input bias current and very small input noise. It features exceptionally low quiescent current and low power dissipation with a wide range of operating frequency. The OP490GSZ operates with a wide supply voltage range of 3V to 12V and has a unity-gain crossover frequency of 101kHz, with a minimum of 0.1Hz of phase margin. It has a low input bias current of 0.2nA and the output impedance is low at 5kΩ, which allows for easy integration with other circuits. Its high common-mode rejection ratio (CMRR) of 87dB further increases the noise immunity of the output. All these features make the OP490GSZ an excellent choice for industrial and instrumentation applications, such as high precision analog signal processing, data acquisition systems and calibration equipment.

The OP490GSZ is a single-supply, dual-channel operational amplifier, capable of operating in both differential and single-ended modes. Its internal signal path is composed of a differential amplifying stage, a current output stage and a low-noise voltage-feedback input stage. The differential amplifier amplifies the signal in the signal path, while the current output stage converts the signal from current to voltage, making it easier for the user to integrate it with other circuits. The low-noise voltage feedback input stage provides a low noise signal into the signal path, improving the accuracy of the output signal. The OP490GSZ can also be configured to operate both as an amplifier and a buffer.

When operated in a differential mode, the OP490GSZ provides a wide common-mode range and high common-mode rejection. This ensures that the signal is accurately amplified, with minimal noise and distortion. The wide common-mode range makes it suitable for applications with high-frequency signals, such as high-speed data acquisition and image processing. Additionally, the OP490GSZ\'s low quiescent current and low power dissipation make it ideal for battery-operated applications with low power requirements. It can also be used to drive multiple loads in parallel, allowing users to easily add additional circuitry to their designs.

When used as a buffer, the OP490GSZ can provide high impedance isolation without degrading the signal integrity, while also increasing the signal-to-noise ratio. This makes it ideal for applications where isolation is required, such as instrumentation systems and data acquisition. The low input bias current and low power consumption make it extremely efficient, while the wide operating bandwidth and low noise make it ideal for high-speed applications.

The OP490GSZ is a versatile, low-voltage operational amplifier designed for industrial and instrumentation applications. It has low power consumption, high differential common-mode range and high common-mode rejection. Its high bandwidth, low noise and low input bias current make it suitable for high-frequency signal processing and data acquisition. Additionally, its low output impedance allows for easy integration with other circuits. These features make the OP490GSZ an ideal choice for instrumentation, data acquisition, and other industrial applications.
