Introduction of Data Acquisition - Analog to Digital Converters (ADC)

Data acquisition (DAQ) is the process of measuring an actual physical phenomenon such as temperature, pressure, or voltage and converting it into digital values for further treatment in computers and other digital systems. An analog-to-digit converter, or ADC, is an electronics device which converts an analog signal (such as a voltage or temperature) into a digital signal (a series of 0s and 1s) that can be understood by a computer or other digital system.Analog-to-digital conversion is essential for monitoring and controlling processes in modern industries. An ADC provides the circuitry and software necessary for measuring analog values, amplifying them, and then converting those analog signals into digital values. The devices vary in complexity, size, and accuracy.An example of an Analog-to-Digital device is the LTC2412IGN#TRPBF. It is used in embedded applications such as systems that need low noise levels and high accuracy. It is designed for applications that require greater resolution than a single-bit ADC. It is a low power, 24-bit, delta-sigma, analog-to-digital converter with differential input and high-speed, low-noise integration. It contains a programmable gain amplifier for increasing the size of the signal coming in and a low-noise operational amplifier for conditioning the input signal.Working Principle of LTC2412IGN#TRPBF

The LTC2412IGN#TRPBF is an analog-to-digital converter that uses Delta-sigma modulation to convert the input analog voltage into a 24-bit digital code. This device has a differential input and a single-ended output. The differential input allows more accurate measurement of small signals by reducing the effects of common-mode noise. The single-ended output makes the device more suitable for applications that require digital outputs.The LTC2412IGN#TRPBF operates in two stages. In the first stage, a programmable gain amplifier (PGA) amplifies the input voltage according to the user-programmed gain setting. The amplifier has a gain range from 1 to 256. This gain setting allows a low level of input voltage to be accurately converted into a digital code.In the second stage, a low-noise delta-sigma analog-to-digital converter (ADC) takes the amplified input voltage, and converts it into a 24-bit digital code using the delta-sigma modulation technique. The ADC has a low noise figure of only 0.8μV, ensuring accurate and stable measurements.Applications of LTC2412IGN#TRPBF

The LTC2412IGN#TRPBF is well suited for embedded applications that require low noise levels, low power consumption and high accuracy. These include:• Automotive sensors, such as oxygen sensors, cam and crank position sensors, and speedometers.• Industrial temperature, pressure, and flow sensors.• Medical applications, such as EEG sensors and imaging systems.• Security cameras and biometric devices.• Environmental monitoring systems.The device is compatible with most microcontrollers and digital signal processors, making it easy to integrate into existing systems. Furthermore, the low power consumption allows the device to be used in battery powered systems without sacrificing accuracy.Conclusion

The LTC2412IGN#TRPBF is a low power, high accuracy, 24-bit delta-sigma analog-to-digital converter with differential input and high-speed, low-noise integration. It is ideal for embedded systems that require low noise levels, low power consumption and high accuracy. The device is compatible with most microcontrollers and digital signal processors, making it easy to integrate into existing systems.
