Analog Devices data acquisition IC simplifies industrial and instrumentation equipment design
Analog Devices has introduced a highly integrated data acquisition IC that 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, 1-MSPS (million-samples-per-second) ADAS3022 data acquisition IC is effective 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 integrates 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). It includes an 8-channel, low-leakage multiplexer and precision low-drift 4.096-V reference. With eight data channels and delivering full 16-bit dynamic range, the new IC is optimised to interface with a wide range of sensors running from ±10 V to as low as ±640 mV.
Supplied in a 6 mm x 6 mm 40-lead LFCSP lead-frame chip-scale package, the ADAS3022 offers a complete factory calibrated and tested signal chain. This addresses the settling time, signal buffering, level shifting, noise amplification/rejection and other analog signal-conditioning challenges that were once a standard part of the system design process.
Recommended Complementary Components
Complementary components for the ADAS3022 include the ADR381 band gap voltage reference, ADR434x XFET voltage reference, ADR454x ultra-low-noise voltage reference, ADP1613/14 step-up PWM switching converter, ADP1715 linear regulator, ADP3334 linear regulator, ADP7102/04 CMOS low-noise LDO, AD8031/32 low power reference buffer, and ADA4841 low power ADC drivers for auxiliary input pair (AUX±). An evaluation board is also available that allows system designers to configure the ADAS3022 without engaging in circuit-board design or writing software code.
