DAQ solution for fast development of precision data acquisition systems

Mouser now stocks the ADAQ7767-1 μModule DAQ solution from Analog Devices, Inc. The 24-bit precision data acquisition (DAQ) μModule system allows the fast development of compact, high-performance precision DAQ systems. The device is ideal for electrical testing and measurement, condition monitoring for predictive maintenance, universal input measurement platforms, audio testing, and other applications that need high-precision data acquisition.

The solution combines signal conditioning, conversion, and processing blocks into a single SiP configuration. The device includes a fourth-order, low-noise, linear-phase AAF to protect the signal chain against high frequencies and out-of-band tones and a low-noise, low-distortion, high-bandwidth, gain-selectable ADC driver. Other features include a high-performance, medium-bandwidth, 24-bit Σ-Δ ADC with a programmable digital filter and a low-noise, LDO linear regulator. The 24-bit precision DAQ μModule system also consists of an optional linearity boost buffer to improve signal chain linearity further.

The device supports various input types, including unipolar, bipolar single-ended, pseudo-differential, and differential signals. The device is ideal for multichannel applications and is designed in a 12mm x 6mm, 84-ball CSP_BGA package with 0.8mm ball pitch. It provides significant space savings with a footprint eight times smaller than a similar solution with discrete components. Three pairs of pin-selectable gain settings allow for a wider dynamic range and improved signal chain noise performance, especially with lower amplitude input signals. The device will enable users to choose the input amplifier that best suits applications requiring high input impedance.

The ADI EVAL-ADAQ7767-1 evaluation kit supports the DAQ solution. The kit is used alongside downloadable evaluation software to configure the ADAQ7767-1's features and display the conversion results in the time and frequency domains.
