Data Conversion is a process used to convert information from one form to another. Analog to Digital Converters (ADCs) are used to achieve this conversion by converting analog electrical signals such as voltages, currents, and tempuratures, into digital data. The AD7880BR is an Analog to Digital Converter designed to convert a wide range of signals into 16 bit digital value. The AD7880BR has a fast sampling time of 7.5μs, a wide input signal range up to ±10V and noise rejection performance up to 50dB, making them an ideal choice for applications involving an array of input signal types.

The AD7880BR has two operating modes; a single-ended mode and a differential mode which allows it to adapt to the signal properties. In single-ended mode the input is referenced to the reference voltage, whereas in the differential mode the two inputs are referenced to each other, allowing for better signal noise rejection.In single-ended mode the user can select one of two input configurations; the conventional or chop modes. In Conventional mode the input signal is measured in relation to the reference voltage, whereas in the chop mode the reference voltage is modulated and the input signal amplitude is measured. This feature helps to reduce the effects of 1/f noise.

In a differential mode the AD7880BR has a common mode rejection of 56dB, and an offset voltage error. This allows the device to be used in applications that require the measurement of differential input signals.The AD7880BR has a wide range of applications including; medical instrumentation, automotive sensor monitoring and control, industrial measurement and data acquisition, and process control systems. Additionally, the low power consumption and wide range of interface options make the AD7880BR suitable for a range of portable or mobile device applications.

To achieve a high level of accuracy, the AD7880BR offers a self-calibration feature. This is a two stage process which corrects any input offset errors and measures the gain. In addition to this, the device also features internal temperature compensation which allows the user to keep the accuracy of the device stable over a wide range of temperatures.

The AD7880BR is an ideal choice for applications that require 16 bit level of accuracy with low noise, fast conversion time and low power consumption. Additionally, with its wide range of features and flexible configuration options, the AD7880BR can be used with a variety of input signal types and offer high reliability in any application.
