The ADAQ23878 is a precision, high speed, μModule® data acquisition solution that reduces the development cycle of a 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 ADAQ23878 reduces end system component count by combining multiple common signal processing and conditioning blocks in a single device, including a low noise, fully differential ADC driver (FDA), a stable reference buffer, and a high speed, 18-bit, 15 MSPS successive approximation register (SAR) ADC.
The ADAQ23878 also incorporates the critical passive components with superior matching and drift characteristics using Analog Devices, Inc., iPassive® technology to minimize temperature dependent error sources and to 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 still provides the flexibility of a configurable ADC driver feedback loop to allow gain or attenuation adjustments, as well as fully differential or single-ended to differential input. A single 5 V supply operation is possible while achieving optimum performance from the device.
The ADAQ23878 features a serial low voltage differential signaling (LVDS) digital interface with one-lane or two-lane output modes, allowing the user to optimize the interface data rate for each application. The specified operation of the ADAQ23878 is from −40°C to +85°C.
