The TLC7628CDW is a Data Acquisition (DAQ) device from Texas Instruments, which employs Digital-to-Analog Converters (DAC) technology to allow for conversion of digital information into analog signals - such as audio and video. This particular device is capable of up to 3.2MS/s sampling rate, 18-bit resolution, and features an advanced built-in dual-channel Sigma-Delta Modulator. The main purpose of the TLC7628CDW is precision analog-to-digital (ADC) conversions, with various use cases ranging from audio/video codecs and industrial automation systems, to process controls and embedded applications.

The device has a wide variety of potential applications and is often used in DAQ projects, such as auto-detecting subsystems and motor control, as well as video streaming and image processing. It is also suitable for a number of applications in the medical field - such as EEG monitoring, medical instrumentation, and digital medical imaging. With its high accuracy and low noise, the device provides excellent performance within the fields it is designed for.

The TLC7628CDW works on the principle of a sigma-delta modulator, which employs an oversampling technique. The circuitry of the converter is designed to drive an input signal for a given number of clock cycles - with each cycle producing an output state of either one or zero. A delta-sigma modulator accumulates these bits over a given period to form a higher bit-depth signal, providing a more accurate representation of the input signal. By processing delta-sigma levels, the original information can be reconstructed into its analog version.

The TLC7628CDW offers a wide range of features, making it a versatile choice for a wide range of applications. The device is capable of digital or analog zero-crossing and gain control of the DAC output for accurate zero-crossing and signal clipping. Furthermore, it features a dual digital output port, allowing for one signal to be sent from the device to two separate destinations. For added versatility, the device can be used in part or full DAC mode, allowing for conversion of signals from digital to analog, as well as from digital to digital.

The TLC7628CDW is an efficient DAC device with a feature set suitable for many DAQ applications. It has a high sampling rate and 18-bit resolution, allowing for accurate data conversion with minimal distortion. The dual digital output port and the gain and zero-crossing control allows for versatile use and its small size ensures that the device is easy to integrate into designs. The TLC7628CDW is ideal for applications including audio/video codecs, medical instrumentation, and industrial automation.
