Analog Devices Unveils ADAS3022 Data Acquisition System IC

Analog Devices (ADI) ADAS3022 data acquisition integrated circuit

Analog Devices announced the ADAS3022 data acquisition integrated circuit. The 16-bit, 1-MSPS ADI IC uses one-third the board space of competing discrete devices. It enables engineers to simplify designs and reduce the size of advanced industrial data acquisition systems. The ADAS3022 is available now in 40-lead LFCSP ((lead-frame chip-scale package). It is priced at $14.95. The chip is ideal for power-line monitors, process and motor control, patient monitoring, and other industrial and instrumentation systems that operate within the ±10-V industrial range.

The ADAS3022 data acquisition IC features ADI’s 16-bit PulSAR successive-approximation A/D converter core with high-impedance input buffers and a 7-stage on-chip PGIA (programmable-gain instrumentation amplifier). The IC includes an 8-channel, low-leakage multiplexer and precision low-drift 4.096-V reference. With eight data channels and full 16-bit dynamic range, the new IC is optimized to interface with a wide range of sensors running from ±10 V to as low as ±640 mV.
