Data Acquisition - Analog to Digital Converters (ADC) have come a long way since their introduction to the world of electronics. One such ADC device is the Texas Instruments TLC1543QDB. It is a 14-bit, 1.5-MHz sampling, low-power ADC with an integrated voltage reference. It is especially suitable for applications such as information measurement, imaging systems, medical instruments, and many more.
The TLC1543QDB has two main components – the ADC and the voltage reference. The ADC comprises of an input sampling capacitor, a high-speed, low power amplifier, a sample-and-hold comparator, an over-voltage detector, and a data slicer.
The voltage reference of the TLC1543 is a stable, low drift CMOS voltage reference that provides an internally fixed reference voltage (2.5V or 3.2V). It has an excellent temperature coefficient and provides operational stability in a wide temperature range. Its internal circuit simplifies the design of the power supply.
The working principle of the TLC1543 is based on successive approximation register (SAR) principles. This ensures fast conversion of an analog input voltage into its digital equivalent. When the ADC device is in operation, the user sets a predetermined reference voltage by connecting the reference voltage pin to the voltage reference. The user then applies an input voltage at the input pin of the ADC. The successive approximation register works by evaluating the input voltage with increasing step sizes against the reference voltage. It then stores the digital value of the analog voltage in the output register and finally the digital output of the device is obtained.
The TLC1543QDB is widely used in many application fields from automotive solutions, to instrumentation, to consumer applications. It can be used for different types of motors for control applications as well as for medical applications such as blood pressure monitoring or to test glucose levels. In imaging applications, it can be used to measure the brightness of an image or to adjust the colors of a picture. It is also useful in industrial and consumer electronics where it can be used to measure current, temperature, pressure, or other values.
In summary, the Texas Instruments TLC1543QDB is a versatile, 14-bit, 1.5-MHz sampling, low-power ADC with an integrated voltage reference. It can be used for a variety of electronic applications such as automotive, medical, imaging, and instrumentation. Its working principle based on SAR principles makes it an efficient device for accurately measuring analog input voltages.
