Tools & Simulations

Virtual Eval - BETA

Virtual Eval is a web application to assist designers in product evaluation of ADCs, DACs, and other ADI products. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, response plots, and more.

Product Details

This evaluation board is obsolete and no longer recommended. The replacement board is the EVAL-AD7192ASDZ.

The EVAL-AD7192EBZ is a fully featured evaluation Board for the AD7192. The evaluation board can be operated in standalone mode ( either battery-powered or with external power supply) or connected to a PC via a standard USB interface. When operated with a PC, software is provided enabling the user to perform detailed analysis of the ADC's performance.

Please note: This Evaluation software does not run on Windows 8 or Windows 10 (USB driver is non-compliant with OS >Windows 7).

Product Details

The EVAL-AD7192ASDZ evaluation kit features the AD7192 which is 4.8 kHz ultralow noise 24-bit sigma-delta (Σ-Δ) ADCs. 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 AD7192 ACE Plugin fully configures the AD7192 device register functionality and provides dc time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.
