Data acquisition is an essential component for obtaining digital data from analog signals or vice versa. Analog-to-digital converters (ADC) provide the interface between an analog signal and the digital domain. The Texas Instruments TLC1543QDBR is an 8-bit low-power, low-voltage, successive approximation (SAR) ADC that can be used for a variety of data acquisition applications. This article will discuss the application field and working principle of the TLC1543QDBR.
The TLC1543QDBR is a component of the TLC15xx family of 8-bit low-power SAR A/D converters. It operates from a single 1.8V to 3.6V supply, consuming only 0.8 mW of power. This makes it suitable for portable applications that require low-power operation. The 8-bit device features an input range of 0V to 1.8V and can convert up to 30ksps. It also features an analog multiplexer and two voltage reference inputs. The device has an on-chip charge redistribution sample-and-hold circuit and the digital output is latched on the rising edge of the Conversion pin.
The TLC1543QDBR is excellent for applications where low power, low voltage and fast conversion times are required. It can be used for various data acquisition applications including precision measurement for calibration, sensor data acquisition, industrial automation, medical instrumentation, and automotive applications. It can also be used with various microcontrollers for data acquisition and control.
The working principle of the TLC1543QDBR is based on the SAR process. The internal block diagram of the device is shown in Figure 1. The circuit comprises of two main components: an analog multiplexer and an 8-bit successive approximation register (SAR) comparator. The analog multiplexer is used to select the input to be measured. The SAR tracks the output of the multiplexer and compares it to the reference voltage at each step of the conversion cycle. At each step the comparator output is checked and the SAR logic adjusts the DAC output accordingly. Once the DAC output is close enough to the reference voltage, the conversion is complete and the 8-bit result is latched on the rising edge of the Conversion pin.
The TLC1543QDBR is well suited to a wide range of data acquisition applications. The low power and low voltage operation make it ideal for portable applications. The fast conversion time of up to 30ksps provides a high speed data acquisition solution. The device is also simple to use and can be easily interfaced with microcontrollers for control and data acquisition.
In conclusion, the TLC1543QDBR is an 8-bit ADC that offers both low voltage and low power operation. It is suitable for a range of data acquisition applications including calibration, industrial automation, automotive and medical instrumentation. The device is based on the SAR process and can achieve conversions up to 30ksps. The very low power consumption makes it an ideal solution for portable applications.
