PCM1744U/2K

ADCs/DACs - Special Purpose Overview

The PCM1744U/2K 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 a serial interface for data input and provides two analog outputs. It operates on a single power supply ranging from 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 97 dB and a gain error of +/- 10% FSR. The component is housed in an SOIC-14 surface-mount package and functions within a temperature range of -25°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 96 kHz maximum sampling rate
• Serial interface compatibility for digital data input
• 97 dB signal-to-noise ratio (SNR)
• Single 5V power supply operation (4.5 V to 5.5 V)

ADCs/DACs - Special Purpose Applications

• High-fidelity audio playback systems
• Professional audio equipment requiring low jitter
• Home theater receivers and amplifiers

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix '2K' against official documentation, as standard listings often reference the tube-packaged PCM1744U. Confirm current production status, as discontinuation notices may apply to this family. Ensure the required packaging format matches inventory availability.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 24-bit DAC with 96 kHz bandwidth is required. Verify that the system design accommodates the SOIC-14 package dimensions. Check if the +/- 10% FSR gain error meets the application's precision requirements compared to higher-accuracy alternatives.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1744 series of audio DACs. It shares architectural similarities with other members like the PCM1742 but differs in sampling rate capabilities and interface specifics. The U suffix denotes the SOIC-14 package variant.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible substitutes are not explicitly confirmed in public sources. Evaluate PCM1742KE for higher 192 kHz performance or PCM1754DBQ for improved THD+N specifications, ensuring interface and package compatibility.
