AD4851 250kSPS Data Acquisition System (DAS)

Analog Devices AD4851 250kSPS Data Acquisition System (DAS) is a fully buffered, four‑channel, simultaneous‑sampling 16‑bit DAS capable of operating at 250kSPS, featuring differential inputs with a wide common‑mode range. Designed to run from a low 5V supply and to support flexible input buffer supply options, the ADI AD4851 uses a precision, low‑drift internal reference and reference buffer. Each channel supports independently configurable SoftSpan ranges, allowing the tailoring of input ranges to the application’s signal swing. This input range tailoring reduces the need for external signal‑conditioning components. The AD4851 also integrates seamless high dynamic range (SHDR) technology, which automatically adjusts the channel’s input signal path gain on each sample, reducing converter noise without affecting linearity.
