What is ADAS3023?
The ADAS3023 is a SAR-based simultaneous sampling analog-to-digital data acquisition system IC manufactured on ADI’s proprietary iCMOS high-voltage industrial process technology that integrates an 8-channel, low leakage track and hold; a programmable gain instrumentation amplifier (four input ranges) 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 highly integrated ADAS3023 IC provides designers with an entire, factory calibrated multiplexed data acquisition signal chain that is specified to operate over the industrial temperature range of -40°C to +85°C. This means that data acquisition system designers no longer need to worry about signal buffering, common mode rejection, level shifting, amplification, rejection of noise, settling times or any of the other analog signal conditioning that was once a standard part of their design process while also allowing smaller form factor, faster time to market and lower costs. As well as tackling the main design challenges, the ADAS3023 delivers high AC and DC performance at 16-bit and offers true high impedance inputs and rejects common mode signals present on the inputs. • 16-Bit, ±3LSB INL min/max • 91.5 dB SNR typical • >500MΩ Input Impedance • 95dB CMRR typical
