The AD7686CRMZRL7 is a high performance, 18-bit, low power, single-channel, successive approximation register (SAR) analog-to-digital (A/D) converter with an on-board reference and I2C/SMBus/PMBus™ interface. It offers outstanding dynamic performance for specific applications, including temperature sensing and consumer grade temperature sensing, as well as industrial process control, power management, and industrial instrumentation-grade measurements. The on-board reference offers a wide operating range of 0.7V to 2.8V with very good accuracy over temperature among Shunt-Voltage Based ICs. The AD7686CRMZRL7 is silicon proven in the market and offers improved power consumption and increased accuracy compared to other devices.

The AD7686CRMZRL7 is primarily used in applications such as process control, power management, industrial instrumentation-grade measurements, consumer-grade temperature sensing, and medical systems. It is well suited for a wide range of sensing applications requiring high accuracy and low power consumption. It is designed for accuracy and low power consumption, as well as for flexibility in application design. It is also designed for a wide range of operating temperatures, ranging from -40°C to +125°C, and extremely low power operation.

The AD7686CRMZRL7 operates over a wide input voltage range, from 0V to 2.8V, and offers a wide range of output resolutions from 8-bit to 18-bit. Its low power consumption and on-board reference are tailored to meet the power and accuracy requirements of applications including temperature sensing, process control, and industrial instrumentation.

The AD7686CRMZRL7 utilizes a successive approximation register (SAR) architecture to convert analog input signals into digital representations. When the input voltage is applied, the SAR compares this input voltage to the value stored in the internal reference. The converter then continues to adjust the value stored in the reference until it is within one step of the analog input voltage. Once the reference voltage is within one step of the input voltage, the internal comparator output is set, indicating completion of the conversion. The AD7686CRMZRL7 acts as an “on-board” reference and uses an oversampling algorithm to provide high accuracy, and can achieve an 18-bit resolution.

The AD7686CRMZRL7 also includes an on-board temperature sensor, which allows the device to accurately monitor its own thermal properties and take corrective action in extreme temperature environments. The temperature sensor can be used to protect the device in applications with high temperatures, and alerts when the temperature exceeds a user specified limit. The AD7686CRMZRL7 also offers superior performance in power consumption and accuracy. It consumes a low 2.9 mW of power during conversions, and offers a total accuracy of ±15 mV over temperature.

The AD7686CRMZRL7 also features an I2C/SMBus/PMBus™ compatible interface that can be used to communicate between the user\'s processor and the on-board microcontroller. This makes it easy to integrate the device into a variety of data acquisition systems. The I2C/SMBus/PMBus™ interface makes it possible to access the device\'s internal registers, giving the user control over configuration and calibration parameters. Additionally, the on-board reference can be used to provide a stable analog reference voltage to other components, which helps achieve accuracy while keeping power consumption low.

In summary, the AD7686CRMZRL7 is a high performance, low power, 18-bit single-channel SAR A/D converter optimized for precision applications in temperature sensing, process control, and industrial instrumentation. Its on-board reference ensures high accuracy and low power operation over a wide input voltage range. The device is designed for a wide range of operating temperatures, and its I2C/SMBus/PMBus™ compatible interface makes it easy to integrate into a variety of data acquisition systems.
