AD7767 24-BIT, 15 MW, 109 DB, 128KSPS ADC EVALUATION TOOLS
(EVAL-AD7767EDZ) USING EVAL-CED1Z

Introduction

The AD7767 is a high performance 24-bit oversampled SAR analog-to-digital converter (ADC). The AD7767 combine the benefits of a large dynamic range and input bandwidth, consuming just 15 mW power.

Ideal for ultralow power data acquisition (such as PCI- and USB-based systems), the AD7767 provide 24-bit resolution. The combination of exceptional SNR, wide dynamic range, and outstanding dc accuracy make the AD7767 ideally suited for measuring small signal changes over a wide dynamic range. This is particularly suitable for applications where small changes on the input are measured on larger ac or dc signals. In such an application, the AD7767 accurately gather both ac and dc information.

The evaluation tools for the AD7767 incorporate:

The combination of the EVAL-AD7767EDZ board, software (available in both Labview source and executable formats) coupled with EVAL-CED1Z allows the user to fully evaluate the AD7767BRUZ device. This analysis includes, AC (FFT) and DC(waveform and histogram plots) analysis and for the first time incorporates an INL evaluation function. See below for the relevant documentation for the system including technical notes, software downloads and evaluation board gerber files.
