The AD7862ARZ-3 is a data acquisition device, a type of Analog to Digital Converter, with a wide range of applications particularly in communications and power management. This 16-bit, low-power device is able to bridge the gap between the two domains, providing a link between the analog and digital worlds, allowing for accurate representation and conversion of analog data into digital data.The device is designed specifically to produce highly accurate and reliable results, with a best-in-class resolution of 16 bits, an ENOB of 14 bits, and a SNR of 89 dB. This accuracy suitably positions the device for use in a variety of analog data acquisition applications, especially those requiring precision and high-resolution measurement. These may include applications involving the monitoring of power or the measurement of temperature and humidity, or those involving the automation of motor control or communication systems.In addition to its precision, the AD7862ARZ-3 also offers excellent power efficiency, with a power consumption of 1.5 mW in normal mode and 2 µW in standby mode, granting it extended battery life and an overall greener impact. The device is also equipped with various established functionalities, such as Overrange and Underrange detection, positive and negative saturation detection, and a digital filtered output for improved noise reduction.The AD7862ARZ-3 is a highly efficient product and can operate within a broad range of supply voltages, from 2.3V to 5.5V. This combined with its two-stage multi-moded architecture grants it compatibility with multiple processors and microcontrollers, allowing it to be easily integrated into almost any system.The two-stage multi-moded architecture allows the device to work with two different and separate Digital-to-Analog (DAC) stages. The first comprises a low-resolution stage, made up of a 12-bit pipelined DAC, providing the core functionality of the device. The second constitutes a carefully designed, high-resolution stage, consisting of a 4-bit looped DAC, which together provides 16-bit precision and outperforms existing devices in the same field.The AD7862ARZ-3 also features a host of other innovative features, such as a unique dynamic compensation that allows for the correction of static and nonlinear errors, and a wide variety of interfacing options for parallel, serial, or both.Above all, the AD7862ARZ-3 is a comprehensive product with superior performance, making it an ideal choice for use in analogue/digital signal acquisition systems, particularly in the communications and power management sectors. Its features and design provide an optimal solution for applications that demand precise and reliable measurement.
