The 24-bit precision data acquisition (DAQ) μModule system enables the fast development of compact, high-performance precision DAQ systems.
The ADAQ7767-1 is ideal for electrical testing and measurement, condition monitoring for predictive maintenance, universal input measurement platforms, audio testing, and other applications that require high-precision data acquisition.
This μModule DAQ solution combines signal conditioning, conversion, and processing blocks into a single system-in-package (SiP) configuration.
The device includes a fourth-order, low-noise, linear-phase anti-aliasing filter (AAF) to protect the signal chain against high frequencies and out-of-band tones, as well as a low-noise, low-distortion, high-bandwidth, gain-selectable analogue-to-digital converter (ADC) driver.
Additional features include a high-performance, medium-bandwidth, 24-bit Σ-Δ ADC with a programmable digital filter and a low-noise, low-dropout (LDO) linear regulator. The 24-bit precision DAQ μModule system also includes an optional linearity boost buffer to improve signal chain linearity further.
The ADAQ7767-1 supports a range of input types, including unipolar, bipolar single-ended, pseudo-differential, and differential signals.
Designed in a 12mm x 6mm, 84-ball CSP_BGA package with 0.8mm ball pitch, the μModule DAQ is ideal for multichannel applications. The ADAQ7767-1 offers significant space savings with a footprint eight times smaller than that of 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. With the ADAQ7767-1, users can choose the input amplifier that best suits applications requiring high input impedance.
The ADAQ7767-1 μModule DAQ solution is supported by the ADI EVAL-ADAQ7767-1 evaluation kit. The kit is used alongside downloadable evaluation software to configure the features of the ADAQ7767-1 and display the conversion results in the time and frequency domains.
The device and evaluation kit are available from Mouser Electronics in the EMEA, Americas and Asia/Pacific regions.
