Analog Devices Inc. EVAL-AD7292SDZ

Overview

EVAL-AD7292SDZ from Analog Devices is a fully featured evaluation board designed to characterize and validate the AD7292 10-bit monitor and control system IC, supporting its 8-channel SAR ADC, four 10-bit DACs, ±1°C internal temperature sensor, and 12 GPIOs. It operates from a single 5 V supply and interfaces with the EVAL-SDP-CB1Z system demonstration platform via SPI for PC-based control and data analysis.

For engineers reviewing the EVAL-AD7292SDZ datasheet, EVAL-AD7292SDZ pinout, EVAL-AD7292SDZ application, or EVAL-AD7292SDZ equivalent, this board enables rapid functional validation of analog monitoring, digital control, and mixed-signal system integration - especially where precision input conditioning, programmable voltage ranges (0–1.25 V / 2.5 V / 5 V), and standalone or SDP-coupled operation are required.

Technical Context

The EVAL-AD7292SDZ implements dual operational modes: serial interface mode using the EVAL-SDP-CB1Z controller (3.3 V logic level, SPI interface with level shifters) and standalone mode with external VDRIVE (1.8 V–5.25 V) applied via J2. It supports up to 1 MSPS sampling via the AD7292's high-speed serial interface.

Input signal conditioning includes buffered channels (VIN0, VIN1, VIN6, VIN7) using AD8066 amplifiers and direct-input channels (VIN2–VIN5) with 22 Ω series resistors and low-pass filter provisions. Output channels VOUT0–VOUT3 connect directly to the AD7292 DAC outputs via 0 Ω resistors, with identical low-pass filter options.

FAQ

What is the primary function of the EVAL-AD7292SDZ?

The EVAL-AD7292SDZ is an evaluation board specifically built to test and demonstrate the AD7292 10-bit monitor and control system IC. It provides full hardware access to all key features - including the 8-channel ADC, four DACs, internal temperature sensor, and 12 GPIOs - enabling engineers to verify timing, accuracy, interface behavior, and system-level integration before committing to custom PCB design. The EVAL-AD7292SDZ supports both PC-connected (via EVAL-SDP-CB1Z) and standalone host-controlled operation.

Does the EVAL-AD7292SDZ require an external controller to operate?

No - the EVAL-AD7292SDZ supports two distinct operating modes. In serial interface mode, it connects to the EVAL-SDP-CB1Z system demonstration platform for PC-based control. In standalone mode, it accepts external digital control signals via the J5 14-pin GPIO header and external VDRIVE (1.8 V–5.25 V) applied to connector J2, allowing direct integration with customer application boards without additional Analog Devices hardware. Both modes are validated in the official user guide.

What input and output voltage ranges does the EVAL-AD7292SDZ support?

The EVAL-AD7292SDZ supports analog input signals from 0 V to 5 V across all eight VIN channels, with programmable full-scale ranges per channel (0–1.25 V, 0–2.5 V, or 0–5 V) enabled by the AD7292's internal reference. Analog outputs VOUT0–VOUT3 deliver 0–5 V signals generated by the AD7292's four 10-bit DACs. Input channels VIN0/VIN1/VIN6/VIN7 are buffered using AD8066 amplifiers; VIN2–VIN5 connect directly with 22 Ω series resistance and optional low-pass filtering.

How is power delivered to the EVAL-AD7292SDZ during evaluation?

Power is delivered via a single 5 V DC supply connected to external connector J3. This supply powers the AD7292 (DVDD and AVDD set to 5 V by default via LK8/LK9 in Position C), the on-board ADP170 LDO regulator, and the AD8066 amplifiers. When used with the EVAL-SDP-CB1Z, VDRIVE is supplied from the SDP board (LK11 in Position A); in standalone mode, VDRIVE must be externally provided via J2. All supplies are decoupled on-board to ensure stable operation.

What software and drivers are required to use the EVAL-AD7292SDZ?

The EVAL-AD7292SDZ requires two software components: the AD7292 evaluation software (installed from the included CD to C:\Program Files\Analog Devices\AD7292) and the EVAL-SDP-CB1Z system demonstration platform drivers. Both must be installed *before* connecting hardware to the PC. The software provides real-time control of ADC/DAC registers, time- and frequency-domain data analysis, and configuration of input ranges, sampling rates, and GPIO states - all specific to the EVAL-AD7292SDZ and its target AD7292 device.
