Data acquisition encompasses the conversion of analog values to digital values, allowing easier handling, analysis and storage of data. An Analog-to-Digital Converter (ADC) is a device that is devoted to this task, converting a continuous voltage from a given source into an integer number with a binary representation, in packets of data. The AD7714AN-5 is a low power, low cost, single channel, differential input ADC that has become a popular choice for data acquisition. It has many applications, in which this paper will discuss each in detail, in addition to the working principle of the chip.
AD7714AN-5 Applications
The AD7714AN-5 has many applications, each of which provide it with its own unique advantages. These applications include;
- Audio: The AD7714AN-5 can be used as an analog-to-digital audio converter for audio applications, providing a low-power option for applications that require minimal power consumption. This chip supports 16-bit, 24-bit and 32-bit conversions, and it is suitable for applications that require accurate audio reproduction.
- Industrial: The AD7714AN-5 also has applications in industrial applications, as it can measure pressure, temperature, and displacement by converting analog signals to digital values. This chip is suitable for harsh environments, as it exhibits a high-level of EMI immunity and has a wide range of operating temperatures. It is also suitable for applications that require high-accuracy measurements, provided by the 12-bit resolution it supports.
- Medical: The AD7714AN-5 is suitable for use in medical-grade applications, as it can be used to measure ECG signals, EEG signals, or any form of medical used signals. This chip also supports high-resolution measurements, allowing for accurate diagnostic results to be obtained.
AD7714AN-5 Working Principle
The AD7714AN-5 follows a successive approximation register (SAR) architecture, which allows it to convert analog signals to digital values quickly and accurately. This architecture consists of a sample-and-hold (S/H) analog front-end, a comparator, a digital SAR and a successive-approximation register (SAR). The S/H part of the architecture samples the input signal and holds it for the duration of the conversion process. The signal is then compared against a reference signal, generating either a high or low result. This result is then stored in the SAR’s register, resulting in the conversion of the analog signal to a digital value. The resulting digital value is then outputted.
The AD7714AN-5 also has an additional feature known as Over-Range Indication (ORI). This feature is used in applications than require the input signal to be over a certain voltage level before it triggers a function. ORI is used to detect when the voltage of the input signal exceeds the configured limit, providing an indication of the situation.
Conclusion
The AD7714AN-5 is a low power, low cost, single channel, differential input ADC that has many applications and great functionality. Its low power requirement makes it ideal for audio and medical applications, while its versatile design makes it useful in industrial and general data acquisition applications. It follows a SAR architecture, which allows it to accurately and quickly convert analog signals to digital values. The Over-Range Indication feature of the ADC further increases its potential applications, making it one of the most popular choices for data acquisition needs.
