Features and Benefits

Full featured evaluation board for the AD7193
PC control in conjunction with the system demonstration platform (EVAL-SDP-CB1Z/EVAL-SDP-CK1Z)
PC software for control and data analysis (time and frequency domain)

Product Details

The EVAL-AD7193ASDZ evaluation kit features the AD7193, is a low noise, complete analog front end for high precision measurement applications. It contains a low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC). The on-chip low noise gain stage means that signals of small amplitude can interface directly to the ADC. The internal clock option provides a compact solution for low BW requirements.

The PC software fully configures the AD7193 device register functionality and provides AC time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation. The AC analysis is also provided by the software, examples of which are; an FFT displaying the first 5 harmonics SNR, SFDR S/N+D and THD.
