ADAS3023 Data Acquisition System

The ADAS3023 from ADI 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 ADI, 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.
