Analog Devices Inc. EVAL-AD7916SDZ

Overview

EVAL-AD7916SDZ from Analog Devices is a dedicated evaluation board for the AD7916 - a 16-bit, 1 MSPS 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, ±2.5 V/7.5 V analog supply rails, and SMA-input analog conditioning for differential or single-ended operation. Designed for precision data acquisition validation in industrial instrumentation and sensor interface applications.

For engineers reviewing the EVAL-AD7916SDZ datasheet, EVAL-AD7916SDZ pinout, EVAL-AD7916SDZ application, or EVAL-AD7916SDZ equivalent, this page delivers verified hardware configuration details, software integration guidance, SDP interface compatibility (EVAL-SDP-CB1Z), power supply routing, jumper settings for AD7916-specific operation, and FFT/histogram-based performance validation methodology.

Technical Context

The EVAL-AD7916SDZ implements a complete analog front-end for 10-lead PulSAR ADCs, with factory-configured unity-gain buffering (ADA4841-1), midscale common-mode generation (VCM), and dual-rail analog supplies (+7.5 V/−2.5 V) derived from an ADP7102/ADP2301 power architecture. It interfaces to the ADSP-BF527 DSP via SPORT protocol and supports both differential (SL10 = A) and single-ended (SL10 = B) input modes per Table 3 of UG-340 Rev. C.

It requires the EVAL-SDP-CB1Z system demonstration platform for USB-based control and data capture, using a 120-pin edge connector. The board accepts external ac/dc sources via SMA connectors J6 and J10, and includes solder links (SL1–SL7, SL10) to configure supply domains, reference routing, and logic-level translation for 5 V ADC outputs to 3.3 V SDP inputs via ADG3304 on 8-lead variants - though AD7916 uses the 10-lead configuration without level shifter.

FAQ

What is the primary function of the EVAL-AD7916SDZ?

The EVAL-AD7916SDZ is a dedicated evaluation board for the AD7916 16-bit, 1 MSPS PulSAR ADC. It provides a complete, calibrated signal chain - including ADR435 reference, ADA4841-1 drivers, ±2.5 V/7.5 V analog supplies, and SMA-input conditioning - enabling accurate dynamic and static performance validation. The EVAL-AD7916SDZ must be used with the EVAL-SDP-CB1Z controller board to operate the AD7916 under real-world conditions.

Which ADCs does the EVAL-AD7916SDZ support besides the AD7916?

The EVAL-AD7916SDZ is part of the 10-lead PulSAR evaluation platform and supports multiple 10-lead SAR ADCs including AD7685, AD7686, AD7687, AD7688, AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984, AD7988-5, AD7989-5, AD7915, and AD7916. Each variant requires correct jumper configuration (e.g., SL10 = A for AD7916 differential mode) and matching U1 device placement per UG-340 Rev. C.

How is the EVAL-AD7916SDZ powered, and what are the voltage requirements?

The EVAL-AD7916SDZ is powered by a supplied 9 V wall adapter, which feeds on-board regulators (ADP7102, ADP2301, ADP7104) to generate +7.5 V, −2.5 V, +5 V, +3.3 V, and +2.5 V rails. Bench power can replace the wall adapter via screw terminals J2/J3, but requires changing solder links SL1, SL2, SL3, SL7, and SL4 to position B. All supplies are decoupled locally, and a single ground plane minimizes noise coupling during high-resolution ADC testing.

Does the EVAL-AD7916SDZ require additional hardware to operate?

Yes - the EVAL-AD7916SDZ requires the EVAL-SDP-CB1Z system demonstration platform to enable USB communication, clock generation (SCLK up to 60 MHz), and data transfer to a Windows PC. It also needs a standard USB A-to-Mini-B cable, and optionally a low-distortion ac source and SMA cables for analog stimulus. Software is installed separately from the Analog Devices website and includes drivers for both the evaluation board and the SDP controller.

What types of performance analysis does the EVAL-AD7916SDZ software support?

The official EVAL-AD7916SDZ software supports time-domain waveform capture, dc/ac histogram analysis (mean, standard deviation, code distribution), FFT-based spectral analysis (reporting SNR, SINAD, THD, SFDR, noise floor), and summary tab consolidation of all metrics. Data is saved in .tsv format for post-processing. The software operates in connected mode (with EVAL-SDP-CB1Z) or standalone mode for offline analysis of previously captured files.
