16-bit, 500 kSPS, Integrated Data Acquisition Subsystem
The ADAQ7980/ADAQ7988 are 16-bit analog-to-digital converter (ADC) subsystems 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 systems 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.
Using the SDI input, the serial peripheral interface (SPI)-compatible serial interface features the ability to daisy-chain multiple devices on a single, 3-wire bus and provides an optional busy indicator. The user interface 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.

The EVAL-ADAQ7980SDZ is an evaluation board designed to demonstrate the low power ADAQ7980 performance and provide an easy to understand interface for a variety of system applications. The ADAQ7980 is a 16-bit analog-to-digital converter (ADC) subsystem that integrates four common signal processing and conditioning blocks into a system in package (SiP) design that supports a variety of applications.
The EVAL-ADAQ7980SDZ can also evaluate the ADAQ7988, despite being populated with the ADAQ7980. To mimic the evaluation of the ADAQ7988 performance, limit the maximum sample rate of the ADAQ7980 to 500 kSPS in the ADAQ798x Evaluation Software.
The evaluation board is ideal for use with the Analog Devices, Inc., system demonstration platform (SDP) board, EVAL-SDP-CB1Z. The EVAL-ADAQ7980SDZ interfaces to the SDP board via a 120-pin connector. SMA Connectors P1, P2, P3, and P4 are provided to connect a low noise analog signal source.
The ADAQ798x Evaluation Software executable controls the evaluation board over the USB through the EVAL-SDP-CB1Z.
A full description and complete specifications for the ADAQ7980 are provided in the ADAQ7980/ADAQ7988 data sheet and should be consulted in conjunction with this user guide when using the evaluation board. Full details on the EVAL-SDP-CB1Z are available on the SDP-B product page.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
