GENERAL DESCRIPTION

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 chan-

nels, and 125 kSPS for eight channels manufactured on the Analog

Devices, Inc., proprietary iCMOS® high voltage industrial process

technology.

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.

The ADAS3023 integrates eight channels of 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 approxi-

mation 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.
