EVAL-AD469x

Overview

The EVAL-AD4696FMCZ and EVAL-AD4692-ARDZ evaluation boards enable quick and easy evaluation of the performance and features of the AD469x family of devices.

The AD4695/AD4696 are compact, 16-channel, 16-bit, 1 MSPS, multiplexed successive approximation register (SAR) analog-to-digital converter (ADC) that enable high performance data acquisition of multiple signals in a small form factor. The AD4697/AD4698 are pin-compatible 8-channel variants.

The AD4692/AD4691 are compact, high accuracy, 16-bit Easy Drive successive approximation register (SAR) ADCs optimized for high-density multichannel precision data acquisition solutions. The AD4693/AD4694 are pin-compatible 8-channel variants.

Features:

• 16-bit resolution

• Up to 1 MSPS throughput rate

• 16 channels (AD4691/AD4692/AD4695/AD4696) or 8 channels (AD4693/AD4694/AD4697/AD4698)

• On-board reference circuitry

• ACE plugin available for device configuration and performance evaluation

• SPI-compatible serial interface

• FMC and Arduino form factor evaluation boards

Applications:

• Optical networking

• Wireless infrastructure

• Industrial automation

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
