Analog Devices Inc. EVAL-AD7466CBZ

Overview

EVAL-AD7466CBZ from Analog Devices is a fully featured evaluation board designed for the AD7466 12-bit and AD7467 10-bit micropower successive-approximation ADCs operating from 1.6 V to 3.6 V supply, supporting up to 200 kSPS throughput, with on-board AD780 (2.5 V/3 V) and REF191 (2.048 V) voltage references, AD8519 input buffer, and AD713 quad op amp for bias-up circuitry - used for precision analog-to-digital conversion validation in low-power sensor and portable instrumentation systems.

For engineers reviewing the EVAL-AD7466CBZ datasheet, EVAL-AD7466CBZ pinout, EVAL-AD7466CBZ application, or EVAL-AD7466CBZ equivalent, this page delivers verified hardware configuration details, supported interface protocols (SPI-compatible serial interface), reference selection options, link-based setup flexibility, and software-controlled data acquisition capabilities via EVAL-CONTROL-BRD2 integration.

Technical Context

The EVAL-AD7466CBZ implements a modular analog signal chain with selectable reference sources (AD780 or REF191), configurable bias-up circuitry (VIN → VBIASED), and dual-supply support (±12 V via J6 or EVAL-CONTROL-BRD2). It supports both standalone operation and controlled evaluation using the EVAL-CONTROL-BRD2 through a standardized 96-way DIN41612 connector (J4).

Thirteen shorting links (LK1–LK13) configure power routing, reference selection, termination, clock edge alignment (SCLK rising/falling), and op amp supply modes. The board includes dedicated SMB sockets (J1–J3) for AIN, VIN, and VBIASED signals, plus external power connectors (J5, J6) and digital/analog ground separation with single-point AGND/DGND tie near the ADC.

FAQ

What is the primary function of the EVAL-AD7466CBZ?

The EVAL-AD7466CBZ is an evaluation board designed exclusively for characterizing the AD7466 (12-bit) and AD7467 (10-bit) micropower SAR ADCs. It provides complete signal conditioning, reference selection, power management, and SPI-compatible interface capability - enabling engineers to validate DC accuracy, AC performance, and system-level integration without custom PCB development. The board is not intended for production use.

Does the EVAL-AD7466CBZ support both AD7466 and AD7467 devices interchangeably?

Yes, the EVAL-AD7466CBZ is explicitly designed as a shared platform for both the AD7466 and AD7467. Its hardware - including reference circuitry, buffering, power routing, and link configuration - accommodates either device. Software configuration files (ad7466.cfg and ad7467.cfg) ensure correct bit depth, sampling limits, and coding format are applied during evaluation of EVAL-AD7466CBZ.

How is the EVAL-AD7466CBZ powered when used standalone?

When operated standalone, the EVAL-AD7466CBZ requires external supplies via J5 (EXT_VDD and AGND) and J6 (EXT_V+ and EXT_V−). J5 provides 1.6–3.6 V for the AD7466/AD7467 and AD8519; J6 supplies ±12 V for the AD713 quad op amp and AD780 reference. All supplies are decoupled with 10 μF tantalum and 0.1 μF ceramic capacitors per the board's power integrity design.

What role do the 13 shorting links (LK1–LK13) serve on the EVAL-AD7466CBZ?

The 13 shorting links configure critical operational parameters: LK1/LK3 enable 50 Ω input termination; LK2 selects AD780 output (2.5 V or 3 V); LK4/LK11 route VDD from AD780 or REF191; LK5 sets bias voltage source; LK6/LK7 select ±12 V source; LK8 selects SCLK edge alignment; LK12/LK13 define AD8519 supply mode. These links allow precise adaptation of EVAL-AD7466CBZ to diverse test scenarios without soldering.

Is PC software included with the EVAL-AD7466CBZ, and what does it provide?

Yes, the EVAL-AD7466CBZ kit includes Windows evaluation software on CD-ROM. It provides full control over sampling frequency (up to 200 kSPS), sample count (1–2048), data format (binary/two's complement), FFT and histogram analysis, real-time waveform display, and data export (raw, binary, FFT). The software loads device-specific configuration files (e.g., ad7466.cfg) to auto-configure power, timing, and coding for EVAL-AD7466CBZ.
