"A high-precision system
needs an excellent
signal chain. The signal
chain is the foundation
for the entire system."
Hao Jie Chan

In many cases, such as industrial or instrumentation devices, engineers must achieve the highest
precision signal chain possible. Precision technology, or a precision signal chain, seeks to deliver
the truest, best resolution signal to the processor. By selecting the best combination of analog
components, precision signal chains achieve high-fidelity signals to offer the best possible
linearity and signal-to-noise ratio (SNR) specifications.
The optimum precision signal chain is achieved through the careful selection and application
of high-precision, discrete components. When combined correctly, the collective use of high-
precision converters, references, and amplifiers can lead to extremely high performance for
sensor-based systems.
ADI helps ease the process of designing with sensors by providing the following:
• Industry-leading precision technology
• Access to expertise through technical collateral and tools
• Investment in new technology and tools that make designing with precision technology
across the signal chain easier and faster.
• A suite of precision signal chains tailored to the most demanding application needs, and
power management solutions to enhance the accuracy and reliability of each signal chain

Across the huge breadth of applications demanding precision signal
chains, engineers must consider not only the individual components
but also how these components interact with each other across the
complete signal chain to achieve the highest performance.
