PCM1744U/2KG4

ADCs/DACs - Special Purpose Overview

The PCM1744U/2KG4 is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device utilizes an enhanced delta-sigma architecture and operates on a single 5V supply, with voltage ranging from 4.5 V to 5.5 V. It provides two analog outputs and communicates via a serial interface. Key performance metrics include a signal-to-noise ratio of 97 dB and a gain error of +/- 10% FSR. The component is housed in a 14-pin SOIC package and functions within a temperature range of -25°C to +85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the EOL status before procurement. The PCM1744U series has been identified as obsolete with discontinuation notifications indicating end-of-life timelines. Ensure availability through authorized channels or consider alternative components if long-term supply stability is required for production.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring 24-bit stereo conversion at 96 kHz with a single 5V supply. Verify compatibility with the host microcontroller's serial interface protocol. Confirm that the SOIC-14 package fits the PCB layout constraints and that the operating temperature range meets environmental requirements.

ADCs/DACs - Special Purpose Part Context

The PCM1744U/2KG4 belongs to the PCM1744 family of audio DACs from Texas Instruments. The suffix 'G4' indicates lead-free construction compliant with RoHS standards. This part is part of Burr-Brown legacy products acquired by TI, designed for high-performance audio conversion tasks.

ADCs/DACs - Special Purpose Replacement Considerations

Due to the obsolete status of the PCM1744U, direct replacements should be evaluated based on pin compatibility and electrical specifications. Consider newer Texas Instruments audio DACs such as the PCM1742 or PCM1747 series for active production alternatives.
