Introduction

The LTC1747CFW#PBF is a high-performance, low-power, low-noise, multi-channel Data Acquisition (DAQ) board which allows the conversion of analog signals into Digital for further processing by an appropriate device such as a computer or microcontroller. It belongs to the Analog to Digital Converter (ADC) category of data acquisition component and widely used in various applications, from automotive to industrial, from medical to consumer electronics.This article will examine the application field and working principle of the LTC1747CFW#PBF ADC.

Application Field

The LTC1747CFW#PBF ADC offers 8 channels of 8-bit or 10-bit data acquisition, with a sample rate of 50 kS/s for 8-bit operation, and 40 kS/s for 10-bit operation. The board has on-board A/D conversion and 14-bit voltage-controlled oscillator (VCO), making it suitable for data acquisition applications such as signal analysis, monitoring, control, testing, etc.The combination of low power consumption, low noise index (SNR), wide power-supply range (2.7V - 5.25V), and temperature range (40°C - 85°C), make it ideal for a variety of applications, such as in medical systems who need to monitor patient vitals on a continuous basis, automotive systems which need to track parameters with precision, or industrial systems which need to monitor multiple signals simultaneously.The board also supports a wide selection of communications protocols (I2C, SPI, UART, etc.), allowing it to work with numerous microcontroller and embedded controller systems.

Working Principle

The working principle of the LTC1747CFW#PBF ADC revolves around the principle of analog-to-digital conversion, which is the process of converting an analog signal into a digital signal. An analog signal is a representation of the physical properties of a voltage or current in a system, which is continuous in nature and can take any value within a specified range. The analog signal is processed through the ADC, which uses techniques such as sampling, quantization, and coding to convert the analog signal into a digital code.The ADC then processes this digital code, which is stored in memory in the form of a binary number (1s and 0s). A microcontroller or other device sourced with this digital signal can then process this information and display it in a more readable format, such as numerical values (e.g., temperature or pressure readings).

Conclusion

The LTC1747CFW#PBF ADC provides precision conversion of analog signals into digital signals, with its low-power, low-noise, 14-bit VCO onboard, and wide variety of serial communication protocols. Its wide range of applications, from automotive to medical, from industrial to consumer electronics, make it a popular choice for a variety of data acquisition applications. The working principle of the ADC revolves around the principle of analog-to-digital conversion, which is the process of converting a continuous analog signal into a digital code for further processing.
