Analog Devices ADAS3022 Data Acquisition IC

Analog Devices ADAS3022 Data Acquisition IC uses one-third the board space of competing discrete devices to help engineers simplify the design and reduce the size of advanced industrial data acquisition systems. The new 16-bit, 1MSPS ADI ADAS3022 is effective for power-line monitors, process and motor control, patient monitoring, and other industrial and instrumentation systems that operate within the ±10V industrial range. This data acquisition IC integrates ADI's 16-bit PulSAR® successive-approximation A/D converter core with high-impedance input buffers and a 7-stage on-chip programmable-gain instrumentation amplifier. ADAS3022 includes an 8-channel, low-leakage multiplexer and precision low-drift 4.096V reference. With eight data channels and delivering full 16-bit dynamic range, this ADI IC is optimized to interface with a wide range of sensors running from ±10V to as low as ±640mV.
