AD7720BRU is a 16-bit low-noise and low-power analog-to-digital converter (ADC) designed for use in high-accuracy, low-power industrial applications. It is an independent, low-power ADC with its own reference input and multiple power-saving features. It features an onboard low-noise amplifier, a flexible input structure and a low-power sleep mode. It is suitable for applications such as data acquisition systems, precision power measurements and weight measurement systems.

The AD7720BRU has a range of selectable input ranges which allows the user to choose which analogue voltage range to use. The dynamic range of this device is 8-bits, so it is able to make a binary decision between two different analogue levels. It also features an internal voltage reference for temperature stability and an on-chip oscillator for the timing system.

The AD7720BRU is based on an R-2R ladder architecture whereby the external number of resistors is far fewer than the resolution of the output. The device has power down and sleep modes with very low power consumption, making it ideal for use in battery-powered applications. Power is saved when the device is inactive due to the low noise amplifier shutting down completely and the low-impedance structure of the device.

The main idea behind the working principle of the AD7720BRU is to convert an analog input signal into a digital value. To do this, the device starts by applying the input signal to a low-noise amplifier which amplifies the signal to a usable level. After that, a comparator is used to compare the input signal against a reference voltage, and based on this comparison, the result is put into a register. After this, the an analogue-to-digital converter uses the register data to convert it into a digital value. This digital value is then used to provide an output in the form of a voltage or a frequency.

The AD7720BRU is mainly used in industrial applications such as weighing scales, precision power measurements, data acquisition systems and temperature monitoring. In these applications, the device is invaluable for providing accurate, low-power and stable measurements. This is due to the low noise amplifier, flexible input structure and power-saving modes.

The AD7720BRU is an ideal ADC for any application that requires low noise, low power consumption, and accurate measurements. Its wide range of selectable input ranges, low-power sleep mode, and robust design make it a great choice for many industrial applications.
