The OPA690IDG4 is a high-performance, low-noise op-amp integrated circuit (IC) specifically designed for use in long-term precision test and measurement applications. It offers outstanding DC accuracy, low distortion and low power consumption, making it ideally suited for analog signal conditioning, instrumentation and data acquisition systems.

The OPA690IDG4 operates in the linear region of the amplifier for a very large majority of the time, ensuring an accurate and low noise output in the presence of a wide range of signal levels. The IC features an adjustable gain bandwidth, making it very versatile, and includes two different feedback circuits for added flexibility. The OPA690IDG4 also features an adjustable output offset voltage control, allowing for fine-tuning the circuit’s static operation.

The OPA690IDG4 is available in both smd and dip packages and runs on a single 5V supply. It is rated for operation up to +105°C and is designed to draw less than 20mA of supply current while in use. The IC is constructed using advanced MOSFET technology and is capable of providing gains up to a whooping 120dB.

The OPA690IDG4’s working principle is based on a differential input stage with a high CMRR (common mode rejection ratio). This gives the IC excellent rejection of signals outside of the device’s specified input range. The amplifier also features low output impedance, making it ideal for applications where there is a need to drive a wide range of loads. The IC’s low noise characteristics ensure a clean signal, even at very low signal levels.

In addition to being used for signal conditioning, instrumentation and data acquisition, the OPA690IDG4 can also be used in a variety of other applications. These include medical technology, automotive systems, audio and video equipment, industrial process control, test and measurement systems and aerospace applications.

The OPA690IDG4 is easily configurable and can be used with a wide range of signal sources, making it very flexible and suitable for a wide range of applications. It is also easily interfaced with other Integrated Circuits (ICs) and microcontrollers, allowing for great flexibility of design. With its excellent DC performance and low power consumption, the OPA690IDG4 is ideal for long term use in precision test and measurement applications.
