Analog Devices Inc. EVAL-AD7763EDZ

Overview

EVAL-AD7763EDZ from Analog Devices is a full-featured evaluation board designed specifically for the AD7763 24-bit Σ-Δ analog-to-digital converter. It supports up to 625 kSPS output data rate, delivers 109 dB dynamic range, and integrates an on-board 4.096 V reference, enabling high-speed precision data acquisition in test and development environments.

For engineers reviewing the EVAL-AD7763EDZ datasheet, EVAL-AD7763EDZ hardware setup, EVAL-AD7763EDZ software interface, or EVAL-AD7763EDZ standalone operation mode, this page provides verified technical context, key specifications, supply and interface requirements, and integration guidance with the EVAL-CED1Z acquisition platform.

Technical Context

The EVAL-AD7763EDZ interfaces directly with the AD7763BSVZ (48-lead LFCSP) via a dedicated SPORT interface routed through a 34-pin connector (J13) to the EVAL-CED1Z board. It relies on the EVAL-CED1Z for FPGA-based digital control, USB communication, clock generation (MCLK), and data capture - though it can operate standalone with user-provided interface logic and power.

Power is supplied externally at 7.5 V via terminal block J2 and regulated onboard by dual ADP3334 LDOs to generate clean 2.5 V (for AVDD1/VDRIVE/DVDD) and 5 V (for AVDD2/AVDD3/AVDD4) rails. Differential analog input is accepted via XLR connector J1 or SMB footprints J5/J6, feeding the AD7763's integrated differential amplifier.

FAQ

What is the required power supply for EVAL-AD7763EDZ?

EVAL-AD7763EDZ requires a 7.5 V DC external power supply connected to terminal block J2. This voltage is internally regulated to 2.5 V and 5 V rails using ADP3334 LDOs. Current draw is ~240 mA in Normal Power mode and ~170 mA in Low Power mode - confirming proper communication with the EVAL-CED1Z when observed on the supply.

Can EVAL-AD7763EDZ operate without EVAL-CED1Z?

Yes, EVAL-AD7763EDZ supports standalone operation, but users must provide all interface logic (SPI/SERIAL), clocking (MCLK), data capture, and host communication. The board lacks onboard USB or FPGA resources - those are supplied exclusively by EVAL-CED1Z in the standard configuration.

How is the AD7763's MCLK signal generated on EVAL-AD7763EDZ?

MCLK is generated by the EVAL-CED1Z board and delivered to the EVAL-AD7763EDZ via link R35. An external clock may be used by installing zero-ohm resistor R10 to route an external source through the clock buffer to the AD7763's MCLK pin - bypassing the EVAL-CED1Z path.

What software is included with EVAL-AD7763EDZ?

EVAL-AD7763EDZ ships with EVAL-AD7763_2EDZ software - a Windows-compatible LabVIEW application that enables real-time waveform display, FFT/histogram analysis, decimation rate control (78–625 kSPS), gain/offset register programming, and custom FIR filter download (12–96 coefficients).

Does EVAL-AD7763EDZ include Gerber files and schematics?

Yes, complete Gerber files and schematic diagrams (Analog, Power, Interface sections) for EVAL-AD7763EDZ are publicly available for download from Analog Devices' AD7763 product page. The board is a 4-layer design with dedicated ground and power planes, and the AD7763's exposed paddle is vias-connected to the internal ground plane.
