Analog Devices Inc. EVAL-AD7606-4SDZ

Overview

EVAL-AD7606-4SDZ from Analog Devices is a dedicated evaluation board for the AD7606-4 16-bit, 4-channel, simultaneous-sampling SAR ADC. It integrates on-board ADP7104ARDZ-5.0 LDO and ADR421 voltage reference, supports up to 200 kSPS sampling, and connects via 120-way SDP interface (J2) to EVAL-SDP-CB1Z for PC-based control and analysis in industrial data acquisition systems.

For engineers reviewing the EVAL-AD7606-4SDZ datasheet, EVAL-AD7606-4SDZ pinout, EVAL-AD7606-4SDZ application, or EVAL-AD7606-4SDZ equivalent, this page delivers verified hardware configuration details, supported signal chain interfaces (SMB analog inputs V1–V6, USB-controlled SDP link), software-defined sampling parameters (769 Hz–200 kSPS, ±10 V range), and system-level integration requirements including external power (7–9 V), SDP board dependency, and Windows-based evaluation software.

Technical Context

The EVAL-AD7606-4SDZ implements a fixed-hardware evaluation platform centered on the AD7606-4 IC mounted at U1. It provides direct SMB connector access to four analog input channels (V1, V2, V5, V6), where V5 and V6 map to AD7606-4's V3 and V4 inputs respectively - matching the device's native 4-channel architecture.

Power delivery uses an ADP7104 5 V LDO regulated from 7–9 V dc input (J1 or J3), with configurable VDRIVE (3.3 V or 5 V via LK3) and SDP-powered operation (enabled by LK2). Link options (LK1–LK3, SL1–SL7) define signal routing for CS, SCLK, CONVST, RESET, STBY, and RANGE configuration - all validated per UG-851 Rev. A for AD7606-4-specific operation.

FAQ

What is the primary function of the EVAL-AD7606-4SDZ evaluation board?

The EVAL-AD7606-4SDZ evaluation board is a complete hardware platform for evaluating the AD7606-4 16-bit, 4-channel, simultaneous-sampling SAR ADC. It includes on-board power regulation (ADP7104), precision reference (ADR421), SMB analog input terminals (V1, V2, V5, V6), and SDP interface (J2) for USB-connected PC control. The EVAL-AD7606-4SDZ enables rapid validation of signal integrity, timing behavior, and dynamic performance under real-world conditions without custom PCB design.

Which ADC does the EVAL-AD7606-4SDZ support, and how are its inputs mapped?

The EVAL-AD7606-4SDZ supports only the AD7606-4 ADC, mounted at U1. Its four analog inputs are accessed via SMB connectors V1, V2, V5, and V6 - with V5 and V6 routed to AD7606-4's V3 and V4 input pins respectively, as explicitly documented in UG-851 Rev. A page 5. This mapping reflects the AD7606-4's native 4-channel structure and differs from 6- or 8-channel variants.

What external hardware is required to operate the EVAL-AD7606-4SDZ?

To operate the EVAL-AD7606-4SDZ, you must use the EVAL-SDP-CB1Z system demonstration platform connected via the 120-way J2 interface, a Windows PC with USB 2.0 port running the AD7606 evaluation software, and a 7–9 V dc power supply (supplied wall adapter or external source). Signal sources connect directly to V1–V6 SMB terminals; no additional ADC drivers or FPGA logic are needed - the EVAL-AD7606-4SDZ handles all biasing, referencing, and digital interfacing internally.

How is the input voltage range configured on the EVAL-AD7606-4SDZ?

The input voltage range on the EVAL-AD7606-4SDZ is set by hardware via resistors R1 and R2 tied to the AD7606-4 RANGE pin. The board ships with R1 installed, connecting RANGE to VDRIVE and enabling ±10 V full-scale range. To switch to ±5 V range, R1 must be removed and R2 installed to tie RANGE to DGND. Software selection in the evaluation GUI must match the physical resistor configuration to ensure accurate amplitude calculations in Waveform, Histogram, and FFT tabs.

Does the EVAL-AD7606-4SDZ support standalone operation without a PC?

No, the EVAL-AD7606-4SDZ does not support standalone operation. It requires connection to the EVAL-SDP-CB1Z SDP board via J2, which in turn connects to a Windows PC via USB 2.0. All control (sampling rate, channel enable, oversampling), data capture, and analysis (waveform, histogram, FFT) are performed through the AD7606 evaluation software - no onboard microcontroller, display, or local storage is included. The EVAL-AD7606-4SDZ is strictly a PC-hosted evaluation tool.
