AD4855 8-Ch Data Acquisition System (DAS)

Analog Devices AD4855 8-Ch Data Acquisition System (DAS) combines a 5V low-voltage supply, flexible input buffer supplies, and differential, wide common-mode range inputs. The fully buffered, 8-channel simultaneous sampling, 16-bit, 250kSPS DAS enables the SoftSpan range of each channel to be independently configured to match the native application signal swing, reducing additional external signal conditioning. The AD4855 integrates seamless high dynamic range (SHDR) technology to further maximize the single-conversion dynamic range. When enabled, the input signal path gain of the channel is automatically optimized on a sample-by-sample basis, minimizing converter noise on each sample without impacting linearity.
