ADAS3022BCPZ

ADAS3022is a complete 16-bit, 1 MSPS, successive approximation analog-to-digital data acquisition system proprietary by Analog Devicesi CMOS® high-voltage industrial process technology manufacturing. The device integrates an 8-channel, low-leakage multiplexer; High impedance programmable gain instrumentation with high common-mode rejectionamplifier(PGIA) class; Precision, low drift 4.096 V reference and buffer; and a 16-bit charge-redistribution analog-to-digital converter (ADC) using a successive approximation register (SAR) architecture. With a ± 15 V supply, the ADAS3022 resolves eight single-ended inputs or four fully differential inputs up to ±24.576 V. In addition, the device can accept commonly used bipolar differential, bipolar single-ended, pseudo-bipolar, or pseudo-unipolar input signals, as shown in Table 1, allowing almost any direct sensor interface to be used.

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