Description

The ADAQ7980/ADAQ7988 are 16-bit analog-to-digital converter(ADC) ?Module? data acquisition systems that integrate four common signal processing and conditioning blocks into a system in package (SiP) design that supports a variety of applications. These devices contain the most critical passive components,eliminating many of the design challenges associated with traditional signal chains that use successive approximation register (SAR) ADCs. These passive components are crucial to achieving the specified device performance.The ADAQ7980/ADAQ7988 contain a high accuracy, low power, 16-bit SAR ADC, a low power, high bandwidth, high inputimpedance ADC driver, a low power, stable reference buffer,and an efficient power management block. Housed within a tiny, 5 mm ? 4 mm LGA package, these products simplify the design process for data acquisition systems. The level of system integrationof the ADAQ7980/ADAQ7988 solves many design challenges, while the devices still provide the flexibility of a configurableADC driver feedback loop to allow gain and/or common-mode adjustments. A set of four device supplies provides optimal system performance; however, single-supply operation is possible with minimal impact on device operating specifications.The ADAQ7980/ADAQ7988 integrate within a compact, integrated circuit (IC)-like form factor key componentscommonly used in data acquisition signal chain designs. The?Module family transfers the design burden of componentselection, optimization, and layout from designer to device,shortening overall design time, system troubleshooting, and ultimately improving time to market.The serial peripheral interface (SPI)-compatible serial interfacefeatures the ability to daisy-chain multiple devices on a single, 3-wire bus and provides an optional busy indicator. The userinterface is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic.Specified operation of these devices is from ?55?C to +125?C.Applications Automated test equipment (ATE) Battery powered instrumentation Communications Data acquisition Process control Medical instruments
