TLC1549IDR

TLC1549IDR is an Analog-to-Digital Converter (ADC). It is manufactured by Texas Instruments and mainly used in data acquisition applications. It is a 8-bit successive approximation ADC with a conversion time of 11µs. It is also known as a Sigma-delta converter.

The TLC1549IDR ADC integrates a comparator, a sample-and-hold amplifier, and a successive approximation register (SAR) into a single monolithic IC. The sample-and-hold amplifier captures the analog input and stores it until the conversion is complete. When the conversion is triggered the internal comparator compares the sample-and-hold amplifier output to a periodically updated internal reference voltage. The period of the reference voltage update is determined by the SAR.

The analog input is sampled by the sample-and-hold amplifier and is held until the conversion is complete. Then, the analog input is compared with the internal reference by the comparator. According to the comparison result, the reference voltage is either increased or decreased. This process continues until the comparator result is equal the internal reference. At this stage the digital output of the conversion is determined. The digital output is the number of times the reference is changed during the comparison process.

The TLC1549IDR is a highly integrated device and it can be used in many data acquisition applications. For example, it can be used in medical imaging systems, industrial control systems, and display systems. It is also suitable for applications where long conversion time is not tolerated such as audio systems.

In summary, the TLC1549IDR ADC is a 8-bitsuccessive approximation ADC from Texas Instruments. It is mainly used in data acquisition applications such as medical imaging systems, industrial control systems, and display systems. Its main feature is its fast conversion time of 11μs.
