The ADS831 is an 8-bit, 80MHz sampling rate analog-to-digital converter. It has high SNR, internal or external reference options, single-ended or differential analog input, programmable input range, low power, low DNL, and single +5V supply, suitable for medical imaging, video digitization, computer scanners, communications and disk drive control applications.
The ADS831 is an 8‑bit, pipeline CMOS analog‑to‑digital converter that operates from a single +5 V supply and offers up to 80 MS/s sampling rate. It supports both single‑ended and differential inputs, programmable input range, and an optional external reference for flexible system design.
The document includes absolute maximum ratings, detailed electrical characteristics, pin‑out diagrams, typical performance graphs, and application notes on input configurations such as AC‑coupled and DC‑coupled designs. Packaging options and ordering information for the SSOP‑20 package are also provided.
