GENERAL DESCRIPTION：

The ADAQ23878 is a precision, high speed, μModule® data acquisition solution that reduces the development cycle of precision measurement systems by transferring the design burden of componentselection, 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 commonsignal processing and conditioning blocks in a single device, including a low noise, fully differential ADC driver amplifier (FDA), a stablereference buffer, and a high speed, 18-bit, 15 MSPS successiveapproximation register (SAR) ADC.The ADAQ23878 also incorporates the critical passive componentswith superior matching and drift characteristics using Analog Devices, Inc., iPassive® technology to minimize temperature dependenterror sources and to offer optimized performance. The fast settlingof the ADC driver stage and no latency of the SAR ADC providea unique solution for high channel count, multiplexed signal chainarchitectures and control loop applications.The small footprint, 9 mm × 9 mm, 0.8 mm pitch, 100-ballCSP_BGA package enables smaller form factor instruments without sacrificing performance. The system integration solves manydesign challenges while the device still provides the flexibility of aconfigurable ADC driver feedback loop to allow gain or attenuationadjustments, as well as fully differential or single-ended to differential input. A single 5 V supply operation is possible while achievingoptimum 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.
