Data Acquisition - Analog to Digital Converters (ADC) is an important technology used to convert an analog signal into a digital signal. Among different types of ADC, the ADC12DJ3200AAV is a 12 bit Successive Approximation Register (SAR) A/D converter that features a maximum sampling rate of 3.2Gsamples/s and a throughput rate of 1.2Gsamples/s. With multiple input channels, low power consumption (6.1mW typical at 3.2Gsps), high resolution, and a programmable dynamic range, the ADC12DJ3200AAV is ideal for a wide range of applications.

ADC12DJ3200AAV Application Field

The ADC12DJ3200AAV flaunts maximum sampling rates as high as 3.2Gsamples/s, making it suitable for use in applications requiring high accuracy, low power consumption, and high speed. This makes it ideal for use in applications such as biomedical imaging and monitoring, electronic defense and surveillance, LTE-Advanced base station receivers, wireless backhaul radio, test and measurement systems, and LTE/Wi-Fi receivers. With the ADC12DJ3200AAV, system designers can be sure of enhanced performance and accuracy, while reducing cost and power consumption.

ADC12DJ3200AAV Working Principle

The ADC12DJ3200AAV utilizes the successful successive approximation register (SAR) A/D conversion method to convert an analog signal into a digital signal. The SAR analog-to-digital conversion technique starts with a voltage reference and a capacitive digital-to-analog converter (DAC) during each clock cycle. After each clock cycle, the ADC12DJ3200AAV compares the analog input signal to the DAC output. This keeps on happening until the analog signal is comparably close to the DAC output. At this point, the difference between the input voltage and the DAC output is the estimated digital value (code) of the analog signal.

The ADC12DJ3200AAV is also capable of simultaneously sampling multiple input channels. It manages to do this via the use of its unique track and hold (T&H) feature. This feature grants the ADC12DJ3200AAV the ability to switch to any of the available channels on the fly. It also implements a particular analog track and hold circuit, which allows the device to receive an analog input signal and hold it using a low power track and hold design.

The ADC12DJ3200AAV also utilizes an embedded 12-bit flash analog-to-digital converter. It is powered by the single 5V supply and its consumption is typically 6.1mW at 3.2Gsps. It also features a programmable power down control which enables users to adjust the output power according to their needs. Moreover, the on-chip voltage reference helps make the system calibration easier.

Conclusion

The ADC12DJ3200AAV is an efficient and cost-effective way to convert an analog signal into a digital signal. With multiple input channels, high resolution, low power consumption, and a programmable dynamic range, it’s suitable for use in a wide range of applications. The SAR A/D conversion technique is a more accurate and reliable way to get accurate results. The embedded 12-bit flash A/D converter, voltage reference, and the track and hold feature allows the ADC12DJ3200AAV to simultaneously sample multiple input channels at a high accuracy and speed, with low power consumption.
