Data Acquisition - Analog to Digital Converters (ADC)

Digital circuit design often requires that analog signals be measured, stored, and transmitted digitally. Analog-to-digital converters (ADCs) can convert these signals into digital values-either discrete variables or word formats-so they can be processed and monitored using digital circuits. The TLV1543IDBR is a 10-bit, high-speed, low-power ADC that features a 500-ns conversion time and is ideal for applications of industrial, healthcare, and communications. It is fully specified over the extended industrial temperature (-40°C to +125°C) range and is available in both 16- and 32-pin packages.

TLV1543IDBR Application Field

The TLV1543IDBR is designed for use in industrial and automotive applications such as industrial controllers, motor control systems, and medical monitoring equipment. It can also be used in portable electronic devices such as portable medical and healthcare equipment, wearable medical devices, and sports and fitness wearables. Additionally, the TLV1543IDBR can be used in communications equipment such as 4G and 5G base station transmitters and receivers, automotive infotainment systems, and wireless access points. Finally, the TLV1543IDBR is a good choice for designers looking to utilize the latest digital-analog-conversion technology to implement advanced function and feature sets in their applications.

TLV1543IDBR Working Principle

The TLV1543IDBR is an 10-bit ADC that has a 500-ns conversion time and can operate at up to 1 Msps. It features a toggling Sine Wave input range and an adjustable voltage reference. The design of the TLV1543IDBR ensures flexibility and convenience for designers who need to integrate a fast and accurate digitizing analog signal into their design.

When operating in a single-channel single-ended system, the TLV1543IDBR allows for direct conversion of the analogue signal to 10-bit digital values. The TLV1543IDBR can be used to measure AC or DC signals, or any mixture of them. It also allows for adjustment of the reference voltage to optimize the dynamic range of the conversion, as well as the ability to filter and sample the input signal up to 125 kSps. The TLV1543IDBR has an internal voltage reference which can be used to adjust the input range of the ADC.

The TLV1543IDBR uses a successive approximation register (SAR) structure to convert the analogue signal. The SAR algorithm works by making an initial estimate of the analog input voltage and then repeatedly evaluating until the estimate is within a specified digital accuracy. The converter then stores the digital output and signal conversions are completed in the order that they are received. Additionally, the TLV1543IDBR features high-speed access to digital results through the Serial Peripheral Interface (SPI).

Conclusion

The TLV1543IDBR is a high-speed and low-power 10-bit ADC which is ideal for applications of industrial, healthcare and communications. It is optimized for industrial and automotive applications, such as industrial controllers, motor control systems and medical monitoring equipment, as well as for portable electronic devices such as portable medical and healthcare equipment, wearable medical devices, and sports and fitness wearables. The TLV1543IDBR uses a successive approximation register (SAR) structure to convert analogue signals and features a toggling sine wave input range and an adjustable voltage reference. Additionally, the TLV1543IDBR has an internal voltage reference which can be used to adjust the input range of the ADC and provides high-speed access to digital results through the Serial Peripheral Interface (SPI).
