Data Acquisition - Analog to Digital Converters (ADC)

The AD7789BRM is a 16-Bit, Sigma-Delta Analog to Digital Converter (ADC) designed to meet the stringent requirements of industrial processes while providing high-resolution performance. The AD7789BRM type of Sigma-Delta converter is a common choice for applications such as data acquisition, test and measurement, and process automation, due to its ability to convert analog signals into digital data with high accuracy and reliability. The AD7789BRM is a low-noise, low-power, low-cost, and high-accuracy ADC that is suitable for both automated and portable systems. The device integrates two low-pass filters – an antialiasing filter and a digital filter – that enable it to accurately sample analog input signals down to DC. The two filters enable the ADC to accurately detect and convert signals of varying frequency and amplitude.The AD7789BRM has a versatile single-ended or differential input and a wide input dynamic range. This enables the ADC to handle signals across a wide range of frequencies and amplitudes. The ADC also has programmable gain and offset, allowing it to accurately measure the input signals across its input range. The AD7789BRM has an operating temperature range of -55°C to 125°C. This wide range enables it to be used in a variety of environments, including extreme temperatures. It also has a high accuracy data conversion rate of up to 160kHz, allowing it to sample data faster and provide more accurate data. The AD7789BRM is a low-power device with a power consumption of only 500 µW. This makes the device suitable for portable and battery-powered applications. The device is also highly reliable, with an operating life of up to one million hours.The main working principle of the AD7789BRM is Sigma-Delta conversion. This type of ADC utilizes a high-speed sampling technique that it is over-sampling input signals, first to a high resolution, and then converting them to digital data. To convert the analog input signal to digital data, the AD7789BRM uses two internal digital filters - an antialiasing filter and a digital filter. The antialiasing filter reduces the noise in the signal and the digital filter outputs the digital data. The AD7789BRM’s features and performance make it an ideal ADC for industrial processes and critical measurement applications. Its programmable gain and offset, wide dynamic range, and high accuracy make it suitable for use in data acquisition systems, test and measurement, process automation, and other industrial applications where single-ended or differential input and low-power consumption are critical. Additionally, its ability to accurately sample signals over a very wide frequency range makes it suitable for applications such as motors and machine control.
