Analog Devices Inc. EVAL-AD7366CBZ

Overview

EVAL-AD7366CBZ from Analog Devices is an evaluation board for the AD7366 dual 12-bit, simultaneous-sampling SAR ADC with true bipolar ±10 V/±5 V/0–10 V input ranges, 1 MSPS throughput, and SPI-compatible serial interface-designed for precision industrial data acquisition systems requiring synchronized analog channel capture.

For engineers reviewing the EVAL-AD7366CBZ datasheet, EVAL-AD7366CBZ pinout, EVAL-AD7366CBZ application, or EVAL-AD7366CBZ equivalent, this board enables rapid validation of AD7366 performance in high-voltage bipolar signal chains, including sensor interfacing, motor control feedback, and power quality monitoring under real-world layout and supply conditions.

Technical Context

The EVAL-AD7366CBZ implements a complete test platform for the AD7366 IC, featuring on-board decoupling (680 nF at DCAPA/DCAPB), configurable RANGE0/RANGE1 logic jumpers, REFSEL selection for internal 2.5 V ±0.2% reference or external 2.5–3.0 V sourcing, and buffered analog inputs VA1/VA2/VB1/VB2 supporting ±12 V operation with external 3 V reference.

It provides direct access to all 24 TSSOP pins-including CNVST-triggered simultaneous sampling, BUSY-driven timing synchronization, and dual DOUTA/DOUTB serial outputs-with dedicated AVCC/DVCC/VDD/VSS power rails, AGND/DGND isolation, and SCLK/CS/ADDR control headers compatible with standard microcontroller SPI peripherals.

FAQ

What is the primary function of the EVAL-AD7366CBZ?

The EVAL-AD7366CBZ is an evaluation board designed exclusively for the AD7366 dual 12-bit simultaneous-sampling SAR ADC. It provides a fully configured hardware environment-including power regulation, reference selection, analog input conditioning, and SPI interface headers-to validate timing, accuracy, noise, and channel matching performance of the AD7366 in real system conditions before integration into final designs.

Does the EVAL-AD7366CBZ support true bipolar input testing?

Yes, the EVAL-AD7366CBZ supports true bipolar input testing for the AD7366 across ±10 V, ±5 V, and 0–10 V ranges using on-board RANGE0/RANGE1 jumpers. With external 3 V reference applied to DCAPA/DCAPB and proper VDD/VSS biasing (≥±11.5 V), it also enables ±12 V bipolar operation as specified in the AD7366 datasheet Rev. D.

Can the EVAL-AD7366CBZ be used with the AD7367?

No-the EVAL-AD7366CBZ is specifically optimized for the AD7366 (12-bit). While pin-compatible with the AD7367 (14-bit), its layout, decoupling, and firmware assumptions align with AD7366 timing (610 ns conversion time) and SNR (72 dB at 50 kHz); AD7367 evaluation requires the EVAL-AD7367CBZ board per Analog Devices' official documentation.

What power supplies are required to operate the EVAL-AD7366CBZ?

The EVAL-AD7366CBZ requires four independent supplies: AVCC/DVCC (4.75–5.25 V), VDD (+11.5–+16.5 V), VSS (−16.5–−11.5 V), and VDRIVE (2.7–5.25 V). These match the AD7366's iCMOS process requirements and enable full-range analog input operation, including ±12 V mode when using an external 3 V reference.

How does the EVAL-AD7366CBZ handle simultaneous sampling verification?

The EVAL-AD7366CBZ exposes the CNVST input and BUSY output to enable precise timing correlation between dual-channel conversions. By triggering CNVST and measuring BUSY assertion/drop, users can confirm sub-1 µs readout latency and verify simultaneous hold-and-convert behavior across VA1/VA2 and VB1/VB2-critical for phase-sensitive applications like motor current sensing or vibration analysis.
