Analog to Digital converters (ADCs) form a core component of almost all digital systems today. From cell phone cameras that recover images from an array of analog signals to medical imaging systems, ADC\'s are found everywhere. The MAX147EVC16-DIP is a 16-bit, arbitrarily programmable, resolution evaluation board from Maxim Integrated Products designed to evaluate the performance of anti-aliasing filters, ADCs, and digital filters.

Overview of the MAX147EVC16-DIP

The MAX147EVC16-DIP evaluation board contains a 16-bit resolution ADC and an anti-aliasing filter made of a switched capacitor process. It is intended for use with the MAX147 evaluation system. This evaluation system contains a PC-based signal generator and a 16-bit S/PDIF digital audio recorder.

The MAX147EVC16-DIP is capable of sampling input analog signals up to 4 Gbps and providing an average sampling performance of 1 GSPS. Paired with the Max147 control software, the evaluation board provides a simple, intuitive and accurate system that allows for a variety of applications. Such included applications include audio and data processing as well as automated test systems.

The MAX147 provided with the MAX147EVC16-DIP is a robust software package that includes two powerful graphical user interface options: PC-based and the Max147 interactive. The comprehensive software-based features offered beyond the evaluation of the MAX147EVC16-DIP evaluation board include the ability to control the sampling rate, adjust the input offset voltage, and evaluate the noise performance of the ADC.

Working Principle

The MAX147EVC16-DIP evaluation board is designed to sample input analog signals and convert them to digital values for processing. The working principle behind this evaluation board is based on a multi-stage filtering process, known as an anti-aliasing filter. This filter is made up of a switched capacitor network containing a series of high pass filters, low pass filters, and band pass filters that act to reduce artifacts in the sampled signal.

The first stage of the anti-aliasing filter is used to reduce signals outside of the desired passband (where the noise energy has the greatest magnitude). The second stage is used to reduce aliasing caused by signal energy near the Nyquist frequency. Finally, the third stage is used to reduce signals far from the desired passband.

Once the analog signals are filtered and sampled, they must be further processed by the ADC in order to be usable digital values. The MAX147EVC16-DIP contains an on-board AD8571 16-bit ADC for performing this task. The ADC is powered by an on-board quartz crystal, and has a sampling range of 0 to 4 Gbps. The ADC operates at +/- 15V for dynamic performance. Finally, the ADC is connected to the MAX147 evaluation system via the sample acquisition cable and is controlled via the Max147 software.

Applications

The MAX147EVC16-DIP is an ideal evaluation board for evaluating the performance of anti-aliasing filters, ADCs, and digital filters. It is suitable for a variety of applications, such as medical imaging, video surveillance, and signal processing. It can also be used to evaluate the performance of audio and data processing systems quickly and accurately. In addition, it is very suitable for automated testing systems thanks to its intuitive and comprehensive control software.

Overall, the MAX147EVC16-DIP evaluation board provides a robust, high quality solution for evaluating the performance of anti-aliasing filters, ADCs, and digital filters. Its intuitive and easy-to-use software, coupled with a high sampling rate, make it the perfect evaluation board for data and audio applications.
