AD7920BRMZ-REEL is a kind of Analog to Digital Converters (ADC). It is a 12-bit successive approximation register (SAR) located in the same die as a dual 16-bit DAC and a full-duplex communication interface, combining with a power supply of 2.7 to 5.25V. This part has extremely low power consumption in both conversion mode and shutdown mode, and the sampling rate is up to 2Msps. With its low cost, it is a reliable and cost-effective solution for extremely low power data acquisition in many applications.

Since AD7920BRMZ-REEL combines ADC and DAC in one, and it is cost-effective for extremely little power applications, it has a wide range of application fields. The main application field, including communication systems, medical devices, battery powered systems, handheld and industrial equipment, motor control, surveillance systems and measuring equipment, etc.

AD7920BRMZ-REEL also has unique features, such as power-down mode, SINC filter, sample and hold, and so on. Additionally, it has 1Msps, 2Msps and buffered distance update operating modes and an external reference voltage source.

The significant feature for AD7920BRMZ-REEL is its working principle that all the components included on the same die. It succeeds a successive approximation of an analog input voltage applied to an input register, which is clocked from a precision internal SAR clock. The output voltage of the SAR drives a controller to compare with an internal reference and generates a logic output based on the comparison result.

The internal reference voltage is always adjusted according to the analog input voltage by an algorithm, and the algorithm causes the SAR to measure the input voltage step-by-step. The result of each comparison is stored in the output register, resulting in a 12-bit conversion. And then the digital output is sent by the dual 16-bit DAC.

AD7920BRMZ-REEL offers a unique combination of features, low power consumption and high resolution that makes it an ideal choice for many consumer and industrial applications, such as digital communication systems, medical devices, battery powered systems, handheld and industrial equipment, motor control, surveillance systems and measuring equipment, etc.
