Working Principle

The AD7951BSTZRL operates by converting an analog input voltage into a 12-bit binary code. It has an internal reference voltage that is used to calibrate the converter. The AD7951BSTZRL uses a 12-bit successive approximation register (SAR) architecture to perform the conversion.

The conversion process begins with the SAR register initialized to zero. The reference voltage is compared to the input voltage and the digital output is adjusted accordingly. The process is repeated for all 12 bits, until the reference voltage matches the input voltage. The final digital output is written to the output latch, which is then sent to the output.

The AD7951BSTZRL is a low power device, which minimizes the amount of power required to perform the conversion. It has a 0.9?A operating current, which is significantly lower than other SAR ADCs. Additionally, it is self-calibrated, so it does not require an external reference voltage to perform the conversion.

The AD7951BSTZRL offers a wide range of features that make it an ideal choice for many applications. It is a low power, precise, and low voltage device that is designed for a variety of applications. This makes it a perfect choice for data acquisition systems where accuracy and low power consumption are important.
