AD4852 250kSPS Data Acquisition System (DAS)

Analog Devices AD4852 250kSPS Data Acquisition System (DAS) is a fully buffered, four‑channel, simultaneous‑sampling DAS that delivers 20‑bit resolution at throughput rates up to 250kSPS, with differential inputs supporting a wide common‑mode range. Powered from a 5V supply and equipped with flexible input buffer supplies, the ADI AD4852 device uses an internal low‑drift precision reference and reference buffer to enable SoftSpan operation, allowing each channel’s input range to be independently programmed to match the signal swing and reduce the need for external signal conditioning. To further enhance performance, the AD4852 incorporates seamless high dynamic range (SHDR) technology, which automatically optimizes channel gain on a sample‑by‑sample basis to minimize noise while preserving linearity.
