Analog to digital converters (ADC) are important parts of most data acquisition systems as they work to convert analog electrical signals into digital signals. The AD9269BCPZ-80 is an example of an ADC specifically designed for high speed, wide bandwidth applications. This article will discuss the application field and working principle of the AD9269BCPZ-80 ADC.

Application Field

The AD9269BCPZ-80 is a wideband, high speed 12-bit ADC offering a serial LVDS interface with a maximum sample rate of 80Msps. It is well-suited for applications requiring reliable, high-speed sampling of wideband signals. Examples of these applications include wireless communication systems, high-speed digitizers, machine vision systems, digital radios, and a variety of other digital signal acquisition systems.

Working Principle

The AD9269BCPZ-80 ADC is based on a “successive approximation” architecture. In this type of system, the incoming analog signal is converted to a digital signal by a successive approximations process. The ADC first samples the input signal and feeds it into a comparator, where it is compared to a “guessing” voltage. This comparison is then used to determine the amplitude of the next “guessing” voltage. This process repeats until the analog signal is accurately represented by the digital “guessing” voltage.

The AD9269BCPZ-80 ADC also employs an integrated tracking digital-to-analog converter (DAC) to improve its linearity. This DAC tracks the analog-to-digital conversion process and helps to ensure that the ADC output remains accurate and that the rate of change in digital sample values accurately reflects the rate of change in the analog input signal.

In addition to its successively approximation architecture, the AD9269BCPZ-80 ADC also features a low power mode and a single 3.3V analog supply. This allows for the ADC to be powered by a single battery, allowing for an efficient and cost-effective power delivery system in power-sensitive applications.

Conclusion

The AD9269BCPZ-80 is a high speed, wideband ADC offering superior resolution and accuracy in applications such as wireless communication systems, radio, machine vision, and more. Its successively approximation architecture, low power mode, and single 3.3V analog supply make it ideal for applications requiring reliable, high-speed sampling of wideband signals.
