Analog Devices Inc. EVAL-AD7983SDZ

Overview

EVAL-AD7983SDZ from Analog Devices is an evaluation board designed to characterize the AD7983 - a 16-bit, 100 kSPS PulSAR® successive-approximation ADC in a 10-lead MSOP package. It provides full signal chain support including on-board ADR435 5.0 V reference, ADA4841-1 ADC drivers, and dual-rail ±7.5 V/–2.5 V analog supply generation. The board enables high-fidelity dynamic testing (SNR, SINAD, THD, SFDR) of the AD7983 in differential or single-ended input configurations.

For engineers reviewing the EVAL-AD7983SDZ datasheet, EVAL-AD7983SDZ pinout, EVAL-AD7983SDZ application, or EVAL-AD7983SDZ equivalent, this page delivers verified hardware architecture, supported ADC variants, software workflow integration with EVAL-SDP-CB1Z, and real-world test setup guidance for precision data acquisition system validation.

Technical Context

The EVAL-AD7983SDZ implements a modular analog front-end with SMA-input J6/J10, unity-gain buffered amplifiers (ADA4841-1), and configurable common-mode voltage (VCM) generation. It interfaces to the ADSP-BF527-based EVAL-SDP-CB1Z via a 120-pin connector using SPORT serial protocol with SCK, SDI, SDO, CNV, and OVDD signals.

Power is derived from a 9 V wall adapter through ADP7102 (+7.5 V), ADP2301 (–2.5 V), and ADP7104 (+2.5 V/+5 V/+3.3 V) regulators. Solder links SL1–SL7 allow bench supply bypass; SL10 selects differential (A) or single-ended (B) input mode per AD7983 configuration.

FAQ

What ADC does the EVAL-AD7983SDZ specifically support?

The EVAL-AD7983SDZ is explicitly configured for the AD7983 - a 16-bit, 100 kSPS PulSAR® ADC in a 10-lead MSOP package. UG-340 lists AD7983 among the 10-lead devices covered and confirms SL10 jumper setting B for its single-ended operation. While the board supports other 8-/10-lead PulSAR ADCs, EVAL-AD7983SDZ refers to the variant populated with AD7983 as the U1 device.

Does EVAL-AD7983SDZ require an external SDP board to operate?

Yes, EVAL-AD7983SDZ requires the EVAL-SDP-CB1Z system demonstration platform to function. The board connects via a 120-pin edge connector and relies on the SDP's ADSP-BF527 processor for SPORT communication, USB interface, and firmware execution. Without EVAL-SDP-CB1Z, no data capture or control is possible - standalone operation is limited to offline file analysis only.

What power supplies are needed for EVAL-AD7983SDZ?

EVAL-AD7983SDZ operates from a supplied 9 V wall adapter. On-board regulators generate +7.5 V (for analog amplifiers), –2.5 V (for negative rail), +5 V (for SDP), +2.5 V/+5 V (for ADC), and +3.3 V (for VDRIVE). Bench supplies can replace the wall adapter using screw terminals J2/J3, but require reconfiguration of solder links SL1–SL7 to B position per UG-340 Table 2.

How is analog input configured on EVAL-AD7983SDZ for the AD7983?

For the AD7983, EVAL-AD7983SDZ uses SL10 set to B (single-ended mode) per UG-340 Table 3. Inputs enter via SMA connectors J6 (IN+) and J10 (IN–), pass through ADA4841-1 unity-gain buffers powered by ±7.5 V/–2.5 V rails, and terminate at the AD7983's IN+ and IN– pins. The default VCM is midscale (2.5 V), enabling 0–5 V single-ended input range referenced to the ADR435 5.0 V reference.

What software tools are provided for EVAL-AD7983SDZ?

Analog Devices provides the "8 & 10 Lead PulSAR ADCs" Windows® GUI software, installed to C:\Program Files\Analog Devices\8 & 10 Lead PulSAR ADCs. It supports real-time waveform capture, FFT analysis (reporting SNR, SINAD, THD, SFDR), DC/AC histogram testing, and summary metrics. Drivers for EVAL-SDP-CB1Z must be installed separately to enable hardware communication.
