AD4858 20-Bit 1MSPS Data Acquisition System (DAS)

Analog Devices Inc. AD4858 20-Bit 1MSPS Data Acquisition System (DAS) is a fully buffered, 8-channel simultaneous sampling DAS with differential, wide common-mode range inputs. Operating from a 5V low voltage supply, flexible input buffer supplies, and using the precision low drift internal reference and reference buffer, the AD4858 allows the SoftSpan range of each channel to be independently configured to match the native application signal swing, minimizing additional external signal conditioning. To further maximize the single-conversion dynamic range, the AD4858 incorporates seamless high dynamic range (SHDR) technology. 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.
