The AD7766 is a high performance 24-bit oversampled SAR analog-to-digital converter (ADC). The AD7766 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 AD7766 provide 24-bit resolution. The combination of exceptional SNR, wide dynamic range, and outstanding dc accuracy make the AD7766 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 AD7766 accurately gather both ac and dc information.
The evaluation tools for the AD7766/66-1/66-2 incorporate:
The combination of the EVAL-AD7766/66-1/66-2EDZ board, software (available in both Labview source and executable formats) coupled with EVAL-CED1Z allows the user to fully evaluate the AD7766BRUZ, AD7766-1BRUZ and AD7766-2BRUZ devices. This analysis includes, AC (FFT) and DC (waveform and histogram plots) analysis. See below for the relevant documentation for the system including technical notes, software downloads and evaluation board gerber files.
