AD976BR Application Field and Working PrincipleThe AD976BR is an analog-to-digital converter (ADC) designed for use in a variety of applications, including data acquisition, process control, and automation. It is one of the smallest and most compact ADC designs available. The AD976BR offers the highest sampling speeds available in a compact size, making it ideal for data acquisition applications with tight physical constraints.The AD976BR features an embedded 18-bit analog-to-digital converter with an Industry standard I2C interface. The converter operates at a maximum sampling rate of up to 10.24Msps. It provides exceptional signal accuracy and wide dynamic range, with an SFDR of 103 dBFS, SNR of 98.3 dBFS, and THD of -109.7 dBFS. The AD976BR is designed to reduce system size and cost with its low power consumption and integrated features. Its low power operation helps save cost, space and power. Its flexible power saving modes approach zero current to saves system power usage. The AD976BR is designed to minimize signal glitches and minimize power consumption by only activating the core when data is transferred. It also has integrated high current drive circuits to support applications needing additional signal drive current.The AD976BR has a wide range of applications such as industrial instrumentation, process control, test and measurement equipment, and data acquisition. This product is suitable for applications where high performance analog input is needed, especially in size and cost-critical applications. In terms of working principle, the AD976BR is an 18-bit ADC with a built-in, dual-slope analog-to-digital converter (ADC). The ADC accepts an analog input signal and converts it into a binary number. The data is then sent through the I2C bus to the ADC\'s interfacing controller. The ADC is capable of sampling input signals up to 10.24Msps. The converted digital signal is output in two-byte big endian format from the ADC and is ready to be filtered or used for further processing. The AD976BR has integrated signal conditioning circuitry, such as external reference voltage, onboard reference voltage source, internal signal clamping, and anti-aliasing filter. The signal conditioning components help to improve signal integrity and accuracy by filtering and clamping signals to eliminate signal distortion and limit signal bandwidth. In conclusion, the AD976BR is an 18-bit ADC that has been designed to provide exceptional signal accuracy and wide dynamic range at maximum sampling rates. The device has a variety of integrated features, such as signal conditioning, flexible power saving modes, and high current drivers, helping to reduce system size and cost. Suitable for applications where high performance analog input is needed, the AD976BR is particularly useful in size and cost-critical applications.
