Analog Devices Inc. EVAL-AD7607EDZ

Overview

EVAL-AD7607EDZ from Analog Devices is an evaluation board for the AD7607 8-channel, 14-bit simultaneous sampling analog-to-digital converter (ADC), supporting true bipolar ±10 V/±5 V inputs, 200 kSPS throughput per channel, single 5 V analog supply, and flexible parallel/serial (SPI/QSPI/MICROWIRE) interface - used to validate high-accuracy power-line monitoring and multiaxis control signal acquisition.

For engineers reviewing the EVAL-AD7607EDZ datasheet, EVAL-AD7607EDZ pinout, EVAL-AD7607EDZ application, or EVAL-AD7607EDZ equivalent, this board enables rapid functional validation of the AD7607 DAS in real-world multiphase motor control, instrumentation, and data acquisition systems - with on-board reference, antialiasing filters, and configurable oversampling modes.

Technical Context

The EVAL-AD7607EDZ implements a complete hardware test platform for the AD7607 IC, featuring direct connection to all 64 LQFP pins via edge-mounted SMA connectors and screw-terminal analog input headers. It integrates the AD7607's internal 2.5 V reference, second-order antialiasing filter (22 kHz cutoff), and 1 MΩ buffered analog inputs - eliminating external op amps or bipolar supplies.

It supports all AD7607 interface modes: parallel (16-bit DB[15:0]), serial (DOUTA/DOUTB), and byte-mode readout, with configurable OS[2:0] oversampling (×2 to ×64), RANGE selection (±10 V/±5 V), and STBY-controlled power-down (25 mW standby, 10 µW shutdown). The board includes jumpers for AVCC, VDRIVE, REF SELECT, and CONVST timing control.

FAQ

What is the primary function of the EVAL-AD7607EDZ?

The EVAL-AD7607EDZ is a dedicated evaluation board for the AD7607 8-channel, 14-bit simultaneous sampling ADC. It provides a fully tested, ready-to-use hardware platform to evaluate the AD7607's performance - including its bipolar input ranges (±10 V/±5 V), 200 kSPS throughput, integrated antialiasing filter, and flexible parallel/serial interface - without requiring custom PCB design. The EVAL-AD7607EDZ enables immediate signal acquisition testing and system-level integration verification.

Does the EVAL-AD7607EDZ support both ±10 V and ±5 V input ranges?

Yes, the EVAL-AD7607EDZ supports both ±10 V and ±5 V true bipolar input ranges via the RANGE pin on the AD7607 IC. A jumper or logic-level signal applied to the RANGE header selects the range: logic high configures ±10 V, logic low configures ±5 V. This matches the AD7607's native capability and is validated across all 8 analog input channels on the EVAL-AD7607EDZ board.

Can the EVAL-AD7607EDZ operate in serial (SPI) mode?

Yes, the EVAL-AD7607EDZ fully supports serial interface operation using the AD7607's SPI/QSPI/MICROWIRE-compatible protocol. With PAR/SER/BYTE SEL set high, the board routes RD/SCLK as SCLK, DB7/DOUTA and DB8/DOUTB as serial data outputs, and CS as frame control. The board includes test points and jumpers to configure clock polarity, phase, and timing - enabling direct connection to FPGAs, DSPs, or microcontrollers.

What power supplies are required to operate the EVAL-AD7607EDZ?

The EVAL-AD7607EDZ requires two independent supplies: a 5 V ±5% analog supply (AVCC) for the AD7607 core and front-end circuitry, and a separate 2.3 V to 5.25 V digital supply (VDRIVE) for the interface logic level - configurable to match host controller voltage (e.g., 3.3 V for FPGA I/O). Both rails are brought out to screw terminals with onboard regulation and decoupling.

Is oversampling supported on the EVAL-AD7607EDZ, and how is it configured?

Yes, oversampling (×2 to ×64) is fully supported on the EVAL-AD7607EDZ via the AD7607's OS[2:0] pins (OS0–OS2), which are accessible through header jumpers. Each combination selects a specific oversampling ratio and corresponding digital filter response - verified in the AD7607 datasheet Rev. D timing tables. The board allows real-time switching between ratios during operation to trade off noise floor vs. throughput.
