AD676JNZ is a 8-bit successive approximation analog-to-digital converter (ADC) designed for a wide range of applications including medical, industrial, consumer and automotive. The converter and its associated circuits are multiplexed to reduce board space, and its excellent dynamic performance is achieved within a 5V supply, offering an unusually wide range of features. The AD676JNZ includes a low power configuration mode, fast conversion time and a high resolution, making it one of the most suitable solutions for any data acquisition or analog-to-digital signal conditioning system.

The AD676JNZ conversion architecture allows for very fast conversion times, and a selectable, single-ended or differential input assures flexibility. The converter can be configured for 4- to 8-bit resolution, suited for a variety of low-level analog signals, including light sensing, digital audio and temperature sensing. Additional features such as low power consumption, selectable power-on reset and a wide range of temperature operating ranges enable applications in limited power environments.

In addition to its fast conversion time and wide range of features, the AD676JNZ integrates a low power management module, providing precise control of power consumption while also ensuring reliable operation. With the Power-On Reset function, the converter can recover from power loss safely and reliably, protecting sensitive equipment from power down surges. A wide temperature range of operation (-40°C to +125°C) and the low power consumption make the AD676JNZ an ideal solution for any application requiring precision analog-to-digital conversion.

The working principle of the AD676JNZ is a successive approximation method. This method works by feeding an analog input voltage into the analog-to-digital converter, where it is digitized. A successive approximation register (SAR) is used to compare the analog input voltage with the binary codes of various known levels in order to find the closest approximation of the binary code. By doing this, the AD676JNZ is able to produce a highly accurate digital conversion from analog input data. The resolution of the converter can be tuned from 4 to 8 bits, depending on the required accuracy.

The AD676JNZ is a very versatile ADC that can be used in a variety of applications. Due to its wide features, low power consumption and high accuracy, it is a perfect fit for applications in the medical, industrial, consumer and automotive markets. Its selectable input allows for measuring single-ended or differential signals, giving it the added advantage of being able to measure a wider range of signals. Additionally, its fast conversion time and power-on reset function make it well-suited for applications that require precise analog-to-digital conversion with reliability and safety.
