AD7707BRU-REEL7 (hereafter referred to as AD7707) is an analog-to-digital converter (ADC) designed exclusively for the industrial market. It is a high-performance part that supports a wide input range, from 0.5 V to 10 V, with a built-in reference voltage of 3.2 V. With a built-in sample-and-hold circuit, it provides the highest accuracy over a wide temperature range of -40°C to +85°C. In addition, the low power design of the device makes it ideal for applications requiring long battery life.

The main application area for the AD7707 is for industrial sensors and monitoring systems. This includes motion sensors, pressure sensors, temperature sensors, strain gauges and load cells that are used in factory automation and security systems. It is especially suitable for applications requiring the highest accuracy, such as those found in medical and scientific equipment. Additionally, the built-in voltage reference makes this part well suited for use in industrial instrumentation and control systems such as computer numerical control (CNC) systems.

The working principle of the AD7707 is relatively straightforward. The unit converts an analog input voltage to a digital value which is expressed in 12- or 16-bit resolution depending on the configuration. The analog input signal is first amplified and then sampled and held for conversion. The unit then performs a successive approximation process to determine the digital equivalent of the input voltage. Once the digital value is determined by the ADC, it is transmitted to the host system via an SPI or I2C port. The value is then interpreted by the host system software to display relevant data.

In summary, the AD7707BRU-REEL7 is a high-performance, low power-consuming analog to digital converter that is perfectly suited to a variety of industrial applications. With its wide temperature range, and high accuracy over a wide range of signal amplitudes, the device is a perfect choice for industrial sensors, monitoring systems, and scientific and medical equipment. The working principle of the part is similarly straightforward, as it converts an analog voltage to a digital equivalent using a successive approximation process.
