Flex Differential ADC - 14 Bit 2MSPS

Anabit's Flex Differential ADC is a powerful open-source reference design that combines precision, flexibility, and speed to elevate your next data acquisition project. Delivering an impressive 14-bit resolution with a 2MSPS sample rate, this design features a front end driver with integrated anti-aliasing filter that ensures high-fidelity signal capture for both pseudo-differential and single-ended applications. Designed with versatility in mind, this ADC reference design not only offers a pseudo-differential input channel (which can be easily reconfigured as single-ended), but also a fully user-configurable second ADC channel without a pre-set driver—empowering engineers to tailor the design to their unique needs. The Flex Differential ADC offers three options for its onboard precision voltage reference: 2.5V, 3.3V, and 4.096V. The onboard precision reference can be accessed externally for integration into external circuits. Example Applications / Use Cases Precision instrumentation – capture low-level differential or single ended sensor signals with confidence High-speed data logging – achieve real-time acquisition up to 2MSPS using standard SPI communication Acoustic and vibration analysis – explore detailed waveforms with clean resolution Industrial / process control applications – motor diagnostics, transient logging, fault detection, general condition monitoring Educational and research labs – an open-source platform for exploring ADC theory of operation, circuit design and firmware control
