The Analog Devices LTC1859CG#PBF is an 8-channel, 16-bit, 100 ksps successive-approximation ADC with software-programmable SoftSpan input ranges, supplied in a 28-lead SSOP package. It accepts single-ended or differential inputs across 0 V to 5 V, 0 V to 10 V, plus-minus 5 V and plus-minus 10 V ranges, includes fault-protected multiplexers and operates from a single 5 V supply. It is intended for multiplexed, multi-channel data-acquisition and process-control systems.
