Data Acquisition - Analog to Digital Converters (ADCs) have come a long way over the years. In order to provide the highest accuracy and resolution for digital signal analysis and data storage, systems can use the LTC2190IUKG#PBF to convert analog signals into digital equivalents. This integrated circuit is built with a high linearity pipeline analog-to-digital converter, an advanced sigma-delta modulator, and a wide range of analog and digital signal conditioning components. This article looks at the application field and working principle of the LTC2190IUKG#PBF.

Overview of LTC2190IUKG#PBF

The LTC2190IUKG#PBF is a low power 10-bit analog-to-digital converter that is able to convert a wide range of input signals. It features a 5ppm/°C drift rate and a ±2.5ppm max error over the full temperature range of -40°C to +85°C. The size of the ADC die is 4.00 x 4.00mm, making it one of the smallest integrated converters on the market. It operates from a single 2.5V or 3.3V supply, with a range of I/O interface options, providing an ideal solution for applications such as high-speed signal analysis.

Application Fields

The LTC2190IUKG#PBF is used in a variety of different applications, such as signal analyzers, test and measurement equipment, data-acquisition systems, and medical equipment. Its high accuracy and resolution make it ideal for applications that require accurate signal analysis, such as those in the aerospace, automotive, and industrial sectors.

The LTC2190IUKG#PBF is also well suited for applications such as radar and automated test equipment (ATE), where high-frequency signals need to be accurately captured and analyzed. Additionally, the low power consumption and wide temperature range makes it perfect for embedded systems.

Working Principle

The LTC2190IUKG#PBF uses an advanced sigma-delta modulator to perform the analog-to-digital conversion process. This modulator works by sampling the input signal at a predetermined frequency. The analog signal is then sent to the ADC\'s decimation filter, which processes the signal and prepares it for conversion. The signal is then converted to a digital equivalent and sent to the ADC\'s digital-to-analog converter (DAC). The DAC then converts the digital equivalent back to an analog signal, which can be used for further analysis or other purposes.

The LTC2190IUKG#PBF also features multiple signal conditioning components, such as a low pass filter, for reducing noise, and an emphasis filter for improving signal to noise ratio. Additionally, the circuit is designed to be tolerant to interference, providing robust performance for applications in high noise environments.

Conclusion

The LTC2190IUKG#PBF is a 10-bit analog-to-digital converter that offers high accuracy and resolution for signal analysis and data storage applications. It operates from a single 2.5V or 3.3V supply and features a wide range of analog and digital signal conditioning components. The LTC2190IUKG#PBF is widely used in signal analysis, test and measurement equipment, data-acquisition systems, and in embedded systems. It uses an advanced sigma-delta modulator to perform the analog-to-digital conversion process, and multiple signal conditioning components to reduce noise and improve the signal to noise ratio.
