The ADAS3023 is a complete 16-bit successive approximation based analog-to-digital data acquisition system. This device is capable of simultaneously sampling up to 500 kSPS for two channels, 250 kSPS for four channels, 167 kSPS for six channels, and 125 kSPS for eight channels manufactured on the Analog Devices, Inc., proprietary iCMOS® high voltage industrial process technology.
The ADAS3023 integrates an 8-channel low leakage track and hold, a programmable gain instrumentation amplifier (PGIA) stage with a high common-mode rejection offering four differential input ranges, a precision low drift 4.096 V reference and buffer, and a 16-bit charge redistribution successive approximation register (SAR) analog-to-digital converter (ADC). The ADAS3023 can resolve differential input ranges of up to ±20.48 V when using ±15 V supplies.
The ADAS3023 simplifies design challenges by eliminating signal buffering, level shifting, amplification and attenuation, common-mode rejection, settling time, or any of the other analog signal conditioning challenges, yet allows for smaller form factor, faster time to market, and lower costs.
The ADAS3023 is factory calibrated and its operation is specified from −40°C to +85°C.

Let's Compare SAR & Δ-Σ Converters for a Mux'd DAS (Planet Analog, 12/2013)
For data acquisition systems, sometimes a successive approximation ADC works best. Other times, a delta-sigma is the best choice. Consideration must also be given to the multiplexer. Let's see what works best and why.
