Overview

Full-featured evaluation board for 8/10 lead PulSAR® ADCs. Versatile analog signal conditioning circuitry. On-board reference, reference buffers and ADC Drivers. PC software for control and data analysis of time and frequency domain.

These low power ADCs offer very high performance of up to 20 bits with throughputs ranging from 100 kSPS to 2 MSPS. The evaluation boards are designed to demonstrate the ADC’s performance and to provide an easy to understand interface for a variety of system applications. A full description of these products is available in their respective data sheets and should be consulted when utilizing the evaluation boards. On-board components include a high precision buffered band gap 5.0V reference (ADR435), reference buffers (AD8032), a signal conditioning circuit with two op-amps (ADA4841-1) and regulators to derive necessary voltage levels on board (ADP3334, ADP3303). SMB connectors are provided for the low noise analog signal source.

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.
