,Introduction to Data Acquisition - Digital to Analog Converters (DAC)
Data acquisition is a process that involves collecting, analyzing, and presenting data that is used for decision making. Data Acquisition systems are essential for the dynamical measurement and monitoring of physical parameters such as temperature, pressure, vibration and flow. One of the most important components of data acquisition systems is the Digital to Analog Converter (DAC). DACs convert digital signals into analog signals which can then be used for measurement and control.LTC2654IGN-H12#PBF Application Field and Working Principle
The LTC2654IGN-H12#PBF is a 6-bit Digital To Analog Converter (DAC) manufactured by Linear Technology Corporation. It is an ideal solution for applications involving precision signal and control signal generation, data acquisition and audio system applications. The LTC2654IGN-H12#PBF supports both unipolar and bipolar output ranges, and is available in a space-saving 5-pin SOT-23 package.The working principle of the LTC2654IGN-H12#PBF is based on the conversion of digital signals into analog signals by the process of Digital to Analog Conversion (DAC). The DAC converts digital input data into an analog voltage or current output. The LTC2654IGN-H12#PBF is based on the conversion of 6-bit digital words into analog voltages. The 6-bit digital words are first decoded into a set of linear current sources. The current sources are then used to drive an external resistor ladder network to generate the corresponding analog voltage output.In addition, the LTC2654IGN-H12#PBF provides temperature calibration and compensation, allowing accurate performance over a wide temperature range. An internal voltage reference and a binary-weighted resistor ladder network provide a total accuracy of 0.2% across the full temperature range.In summary, the LTC2654IGN-H12#PBF is an ideal solution for high resolution applications requiring low noise, low power consumption and a small package size. The DAC is suitable for a variety of precision signal generation and measurement processes such as audio system applications, data acquisition, temperature calibration and temperature compensation.
