Analog to Digital Converters (ADC) are essential components in almost any electronic system. They can take an analog signal and a digital signal, and convert them into a digital signal. One such ADC is the AD7904BRU-REEL. This ADC is specifically designed for easy and cost-effective conversion of analog signals into digital signals. This article will discuss the application field and working principle of the AD7904BRU-REEL.
Application field and working principle of the AD7904BRU-REEL
The AD7904BRU-REEL is an 8-bit, ultra-low power, low noise, analog-to-digital converter (ADC) with a 5µA shutdown mode. Its 5V reference voltage makes it ideally suited for use with most industry-standard devices, including resistive and capacitive ICs, transducers, and other industrial sensors. The ADC features a 16-bit successive-approximation register (SAR) that performs up to 10 MS/s conversion speeds. It has a spread-spectrum mode to reduce EMI and other RF noise, as well as programmable thresholds and offset compensation.
The AD7904BRU-REEL has a wide variety of applications in the industrial, medical, and consumer markets. It is designed to be used in harsh environments, where it can withstand temperatures up to 125°C. This makes it ideal for applications in extreme environment conditions such as automotive, aerospace, and defense.
The working principle of the AD7904BRU-REEL is simple and straightforward. The device has an input differential amplifier that amplifies the input signal. The input signal is sam¬pled and converted to a digital equivalent by the internal SAR. The SAR is then clocked with a 16-bit frequency, 64-bit free running counter that advances starting with 0x0000, and incrementing. The SAR generates a value at each clock cycle and then compares it with the incoming signal. This comparison process is repeated until the input and the reference signals match, and the final output data is the digital equivalent of the analog voltage.
Once the output is ready it is then multiplexed to the 8-bit ADC data pins by the output latch and buffers. The device also has an internal clock generator, which can be controlled externally. This is done by using a clock input pin that can be connected to an external clock source, as long as it is within the frequency range of the AD7904BRU-REEL.
Conclusion
The AD7904BRU-REEL is an 8-bit, ultra-fast, low-noise, analog-to-digital converter that is designed to take an analog signal and convert it into a digital signal. Its wide variety of applications make it an ideal choice for a variety of applications, including automotive, aerospace, and defense. Its working principle is simple and straightforward, making it easy to use and cost-effective.
