Product Details

The ADAS3022 is a complete 16-bit, 1 MSPS, successive approximation–based analog-to-digital data acquisition system, which is manufactured on Analog Devices, Inc., proprietary iCMOS® high voltage industrial process technology. The device integrates an 8-channel, low leakage multiplexer; a high impedance programmable gain instrumentation amplifier (PGIA) stage with high common-mode rejection; a precision, low drift 4.096 V reference and buffer; and a 16-bit charge redistribution analog-to-digital converter (ADC) with successive approximation register (SAR) architecture. The ADAS3022 can resolve eight single-ended inputs or four fully differential inputs up to ±24.576 V when using ±15 V supplies. In addition, the device can accept the commonly used bipolar differential, bipolar single-ended, pseudo bipolar, or pseudo unipolar input signals, as shown in Table 1, thus enabling the use of almost any direct sensor interface.

The ADAS3022 simplifies design challenges by eliminating signal buffering, level shifting, amplification/attenuation, common-mode rejection, settling time, and any other analog signal conditioning challenge while allowing a smaller form factor, faster time to market, and lower cost.
