Analog Devices Inc. EVAL-AD7605-4SDZ

Overview

EVAL-AD7605-4SDZ from Analog Devices is a full-featured evaluation board designed to characterize the AD7605-4 - a 16-bit, 4-channel, simultaneous-sampling SAR ADC with 300 kSPS throughput, on-board 5 V LDO (ADP7104ARDZ-5.0), and high-precision ADR421 voltage reference. It supports standalone operation when paired with the EVAL-SDP-CB1Z system demonstration platform and enables rapid validation of analog input performance in data acquisition systems.

For engineers reviewing the EVAL-AD7605-4SDZ datasheet, EVAL-AD7605-4SDZ pinout, EVAL-AD7605-4SDZ application, or EVAL-AD7605-4SDZ equivalent, this page delivers verified hardware interface details, software-controlled test capabilities (waveform capture, histogram, FFT), and precise configuration guidance for evaluating the AD7605-4's 4-channel simultaneous sampling, ±10 V input range, and serial interface timing under real-world signal conditions.

Technical Context

The EVAL-AD7605-4SDZ interfaces directly with the AD7605-4 via a fixed U1 socket and uses a 120-way SDP connector (J2) to link to the EVAL-SDP-CB1Z. Power is delivered through J1 (7–9 V dc) or J3 (7–9 V external), regulated to 5 V by the ADP7104 LDO and distributed to both the AD7605-4 and SDP board via LK2.

Signal routing supports four analog inputs (V1, V2, V5, V6), mapped to AD7605-4 channels CH1–CH4 respectively. Link options LK3 (VDRIVE = 5 V), SL1–SL7 (CS, SCLK, STBY, RESET, CONVST) allow flexible control sourcing between SDP and SMB connectors, enabling both automated PC-based testing and manual bench verification.

FAQ

What is the primary function of the EVAL-AD7605-4SDZ?

The EVAL-AD7605-4SDZ is an evaluation board specifically configured to test and validate the AD7605-4 16-bit, 4-channel, simultaneous-sampling SAR ADC. It provides complete signal chain support-including on-board 5 V regulation (ADP7104), precision 2.5 V reference (ADR421), configurable VDRIVE, and direct analog input terminals (V1, V2, V5, V6)-enabling engineers to verify dynamic performance (SNR, SINAD, THD), linearity, and timing behavior of the EVAL-AD7605-4SDZ target device under controlled lab conditions.

Which host interface does the EVAL-AD7605-4SDZ require to operate?

The EVAL-AD7605-4SDZ requires the EVAL-SDP-CB1Z System Demonstration Platform (SDP) board, connected via its 120-way J2 connector. The SDP board bridges USB 2.0 communication from a Windows PC (Vista or 7) to the EVAL-AD7605-4SDZ, enabling full control through Analog Devices' AD7606 evaluation software. No standalone USB interface is built into the EVAL-AD7605-4SDZ itself.

Can the EVAL-AD7605-4SDZ evaluate other ADCs besides the AD7605-4?

No - while the EVAL-AD7605-4SDZ shares mechanical and software compatibility with other boards in the EVAL-AD760xSDZ family (e.g., EVAL-AD7606SDZ), it is populated exclusively with the AD7605-4 at U1 and configured for its specific 4-channel input mapping (V1/V2/V5/V6 → CH1–CH4). Its hardware layout, jumper settings (e.g., LK3 for 5 V VDRIVE), and firmware calibration are optimized solely for the AD7605-4, not for AD7606, AD7607, or AD7608 variants.

What input voltage range does the EVAL-AD7605-4SDZ support for the AD7605-4?

The EVAL-AD7605-4SDZ supports a ±10 V input range for the AD7605-4, achieved by populating resistor R1 to tie the RANGE pin to VDRIVE. This hardware configuration matches the default setting in the evaluation software's "5V / 10 V Range" dropdown. Using R2 instead would configure ±5 V range, but the board ships with R1 installed and all documentation assumes ±10 V operation unless explicitly modified.

Does the EVAL-AD7605-4SDZ include power supply hardware?

Yes - the EVAL-AD7605-4SDZ includes on-board power conditioning: an ADP7104ARDZ-5.0 low-noise LDO generates a clean 5 V supply from 7–9 V input (via J1 or J3), decoupled with 10 μF tantalum and 100 nF ceramic capacitors. It also supplies 5 V to the EVAL-SDP-CB1Z via LK2. A 9 V wall-mount switching adapter is included in the kit, making the EVAL-AD7605-4SDZ fully operational without external power design effort.
