Reference Design DAQ Systems
Reference Design Spotlight on Precision Data Acquisition (DAQ) Systems
Precision DAQ systems require resolutions ranging from 16- to 24-bits, with sampling rates from a few Hz to several MHz. Choosing the proper ADC is an important design consideration, as well as the supporting circuitry, including the voltage reference, input drive amplifier, instrumentation amplifier, multiplexer, and power supply. Circuits from the Lab reference designs featured in the table below enable quick integration and evaluation, while expanding your knowledge of precision DAQ and signal chain design.

About Circuits from the Lab® Reference Designs
These signal chain designs are commonly used as standalone solutions, or to build more complex circuits and subsystems.
Built and tested for function and performance by ADI's applications experts, they offer:
- Comprehensive documentation
- Complete design and integration files
- Factory-tested evaluation hardware
