ADAQ23876 μModule® Data Acquisition Solution

ADI's ADAQ23876 precision, high-speed, μModule data acquisition solution reduces the development cycle of precision measurement systems by transferring the design burden of component selection, optimization, and layout from the designer to the device.

Using system in package (SiP) technology, the ADAQ23876 reduces end system component counts by combining multiple common signal processing and conditioning blocks in a single device. These blocks include a low noise, fully differential ADC driver (FDA), a stable reference buffer, and a high speed, 16-bit, 15 MSPS successive approximation register (SAR) ADC.

The ADAQ23876 also incorporates the critical passive components with superior matching and drift characteristics using iPassive® technology from Analog Devices, Inc., to minimize temperature-dependent error sources and offer optimized performance. The fast settling of the ADC driver stage and no latency of the SAR ADC provide a unique solution for high channel count multiplexed signal chain architectures and control loop applications.

The small footprint, 9 mm × 9 mm BGA package enables smaller form factor instruments without sacrificing performance. The system integration solves many design challenges while the device provides the flexibility of a configurable ADC driver feedback loop to allow gain or attenuation adjustments and fully differential or single-ended to differential input. A single 5 V supply operation is possible while achieving optimum performance from the device.

The ADAQ23876 features a serial LVDS digital interface with one or two-lane output modes, allowing the user to optimize the interface data rate for each application.
