Tools & Simulations

Precision ADC Driver Tool

The Precision ADC Driver Tool is a web application that simulates the performance of precision ADC and driver combinations. Potential issues with driver selection, kickback settling, and distortion are flagged, and design tradeoffs can be quickly evaluated. Simulations and calculations include system noise, distortion, and settling of the ADC input

EVAL-AD7982-PMDZ

18-Bit, 1000 kSPS PulSAR® ADC PMOD Evaluation Board

Features and Benefits

  • 18-Bit Analog to Digital Converters
  • 1000 kSPS
  • Unipolar, Differential Input
  • Standard SPI PMOD header/pin out
  • Connectable to 3rd Party FPGA and MCU Platforms

Product Details

The PMOD-compatible evaluation/prototyping board is a small form factor, low-cost analog-to-digital conversion option. When prototyping, this board is used in conjunction with your favorite MCU or FPGA development board which has the SPI PMOD peripheral connector. Direct electrical and physical connection will enable you to quickly develop software for your system.

This board can also be operated as an evaluation board using the System Demonstration Platform (EVAL-SDP-CB1Z) and an adaptor board (SDP-PMD-IB1Z). When operated with the System Demonstration Platform, a LabView software GUI is provided enabling the user to perform analysis of the ADC's performance.
