The ADA4939-2YCP-EBZ evaluation board from Analog Devices is an outstanding integrated amplifier for high speed data acquisition systems, featuring a wide range of operational features for complex analog signal conditioning. Developed for both in-circuit and bench-top testing, this board offers an unprecedented level of flexibility and performance for data acquisition, enabling designers to create a comprehensive pre-amplifier out of a single integrated solution. In this article, we’ll look at the application domain of the ADA4939-2YCP-EBZ, and how its various elements power a number of unique processing capabilities.

The ADA4939-2YCP-EBZ serves as an ideal platform for a wide range of applications where high speed, accuracy, and low power consumption are critical factors. It is designed to provide reliable signal amplification, handling input signals ranging from 0.1 Hz to 10 kHz in frequency and up to 12 kHz in gain and output offset. It is also capable of handling dynamic measurements, filtering out high frequency noise, and boosting signal strength. In addition to its versatile properties, it also offers excellent power efficiency, consuming only a mere 0.6 W in total. This power efficiency makes it ideal for applications that need to process extremely small amounts of energy, such as for use in medical implantable devices.

At the core of ADA4939-2YCP-EBZ’s performance is its proprietary dual low-noise, high-speed amplifier. This amplifier combines two independent amplifiers: a common-mode unmatched one of ±2.0 V and one with matched common-mode range of ±2.5 V. The combination of these amplifiers provides superior performance and flexibility in both signal amplification and dynamic signal measurement. Additionally, the board also contains multiple phase-compensation elements for improved dynamic response, significantly enhancing its ability to accurately capture signals of different frequencies.

The ADA4939-2YCP-EBZ also offers a wide range of operational features that enable it to process signals in a number of different ways. Their output stage is able to support up to +/- 35 V DC offset, expanding the range of input signals the board can process from 0.1 Hz to 10 kHz. In addition, it has an adjustable input gain for fine-tuning adjustments, allowing users to better control the signal-to-noise ratio of the amplifier. Additionally, the board also provides a wide selection of drop-in precision voltage references, adjustable to the user’s needs.

The ADA4939-2YCP-EBZ evaluation board is an ideal platform for a range of high speed, accurate analog signal conditioning applications. Its range of operational features and wide selection of adjustable settings makes it one of the most versatile boards available for data acquisition. Its ability to accurately process signals of different frequencies and support a wide range of input offsets makes it an excellent option for applications where power consumption and accuracy are top priorities.
