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

Product Details

The EVAL-AD4030-24FMCZ evaluation board enables quick and easy evaluation of the AD4030 family of 24-bit precision successive approximation register (SAR) analog-to-digital converters (ADCs).

The AD4030-24 is a low power, 24-bit precision SAR ADC that supports up to 2 MSPS. The evaluation board demonstrates the performance of the AD4030-24 and provides a configurable analog front end (AFE) for a variety of system applications.

The EVAL-AD4030-24FMCZ evaluation board is designed for use with the Digilent ZedBoard. The ZedBoard is used to control data capture and buffering. The evaluation board connects to the ZedBoard board via a field-programmable gate array (FPGA) mezzanine card (FMC) low pin count (LPC) connector. The ZedBoard hosts a Xilinx Zynq7000 SoC, which has two processor cores and programmable FPGA fabric. The ZedBoard connects to the PC through USB.

The evaluation board includes:

A high precision buffered band gap 5 volt reference (LTC6655).
An analog front end (AFE) that provides signal conditioning and drive for the AD4030-24. The AFE can be configured to use either the ADA4896-2 in a dual buffer configuration, or the ADA4945-1, a fully differential amplifier.
An optional 100 MHz clock source that provides a reference clock for the FPGA and ADC.
Full power supply solution that provides all the necessary voltage rails from a 12 volt supply that is provided from the ZedBoard through the FMC connector.

Full descriptions of these products are available in their respective data sheets, which should be consulted when using the evaluation board.
