The ADAQ7980/ADAQ7988 are 16-bit analog-to-digital converter (ADC) μModule® 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 input impedance 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 integration of the ADAQ7980/ADAQ7988 solves many design challenges, while the devices still provide the flexibility of a configurable ADC 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 components commonly used in data acquisition signal chain designs. The μModule family transfers the design burden of component selection,optimization, and la...
