Analog Devices Inc. EVAL-ADAQ7980SDZ

Overview

EVAL-ADAQ7980SDZ from Analog Devices is a full-featured evaluation board for the ADAQ7980 16-bit, 1 MSPS μModule® data acquisition system in LGA package. It integrates on-board reference (5 V/3.3 V), ADC driver circuitry, reference buffers, and power regulation (±2.5 V, +3.3 V, +5 V, +7.5 V) to support flexible analog signal conditioning and high-fidelity sampling in precision measurement applications.

For engineers reviewing the EVAL-ADAQ7980SDZ datasheet, EVAL-ADAQ7980SDZ pinout, EVAL-ADAQ7980SDZ application, or EVAL-ADAQ7980SDZ equivalent, this page delivers verified hardware interface details, SDP-B compatibility (EVAL-SDP-CB1Z), USB-controlled operation via ADAQ798x Evaluation Software, and configurable analog input paths including unity-gain buffer, inverting amplifier, and level-shifted configurations.

Technical Context

The EVAL-ADAQ7980SDZ interfaces directly with the EVAL-SDP-CB1Z system demonstration platform via a 120-pin connector and uses SPORT serial communication from the ADSP-BF527 DSP for conversion control and data readback. It supports both SDP-controlled mode and user-defined control mode using test points or P8 connector.

Hardware configurability includes jumper-selectable reference sources (ADR4550BRZ at 5 V or ADR3433ARJZ at 3.3 V), dual-supply (±2.5 V) or single-supply (ground-referenced V−) operation, and dynamic power scaling via PD_REF, PD_AMP, and PD_LDO signals routed from the SDP board.

FAQ

What is the primary function of the EVAL-ADAQ7980SDZ?

The EVAL-ADAQ7980SDZ is an evaluation board specifically designed to demonstrate and validate the performance of the ADAQ7980 μModule data acquisition system. It provides complete signal conditioning, reference, power, and digital interface infrastructure - enabling engineers to rapidly assess 16-bit, 1 MSPS sampling accuracy, noise floor, THD, and SNR in real-world configurations without custom PCB design. The EVAL-ADAQ7980SDZ also supports evaluation of the pin-compatible ADAQ7988 at reduced 500 kSPS sample rates.

Which controller board is required to operate the EVAL-ADAQ7980SDZ?

The EVAL-ADAQ7980SDZ is designed for use with the Analog Devices EVAL-SDP-CB1Z system demonstration platform (SDP-B). It connects via a 120-pin edge connector (P8) and relies on the ADSP-BF527 DSP on that board to manage SPORT-based conversion triggering, data capture, and power-down signaling (PD_REF, PD_AMP, PD_LDO). While user-defined control mode is supported via test points or P8, full GUI functionality and automated analysis require the EVAL-SDP-CB1Z and ADAQ798x Evaluation Software.

Can the EVAL-ADAQ7980SDZ evaluate both the ADAQ7980 and ADAQ7988?

Yes - the EVAL-ADAQ7980SDZ is populated with the ADAQ7980 but is fully capable of evaluating the ADAQ7988 as well. To emulate ADAQ7988 behavior, users must limit the maximum sample rate to 500 kSPS in the ADAQ798x Evaluation Software. Both devices share identical pinout, reference architecture, power requirements, and signal chain topology; the key difference is maximum throughput, making the EVAL-ADAQ7980SDZ a unified platform for either variant.

What analog input configurations does the EVAL-ADAQ7980SDZ support?

The EVAL-ADAQ7980SDZ supports four factory-configurable ADC driver modes via jumpers J1–J3: noninverting unity-gain buffer, inverting amplifier with level shift, noninverting amplifier with nonunity gain, and noninverting unity-gain buffer with level shift. These are implemented using discrete resistors (R20–R24) and jumpers to set gain, dc bias (VCM), and input topology - allowing direct connection of single-ended or differential sources while maintaining optimal common-mode and full-scale range alignment with the selected reference voltage.

How is power delivered to the EVAL-ADAQ7980SDZ?

The EVAL-ADAQ7980SDZ accepts power via a 9 V dc wall adapter (included) or an external bench supply through the P6 terminal block. On-board regulators generate +7.5 V (for V+ and VDD), −2.5 V (for V−), +3.3 V (for VIO), and +5 V (for SDP interface) using ADP7118, ADP7182, and ADP2370 ICs. Link settings (e.g., J11, J16, J19) allow reconfiguration for single-supply operation (V− tied to ground) or alternate rail voltages - all verified in the UG-1060 user guide and schematics.
