PCM1748KE/2K

ADCs/DACs - Special Purpose Overview

The PCM1748KE/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 an enhanced multi-bit delta-sigma architecture and includes an integrated PLL for clock recovery. It communicates via an SPI interface and operates on a single 5V supply, with voltage ranging from 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 100 dB and a gain error of +/- 6% FSR. The component is housed in a compact SSOP-16 package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'KE' against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required SPI interface timing and power supply constraints (4.5 V to 5.5 V). Confirm that the 96 kHz maximum sampling rate meets system requirements.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 24-bit stereo DAC with integrated PLL is required for 5V analog/digital systems. Compare SNR and THD+N specifications against alternative PCM17xx series devices if higher sampling rates or different interface protocols are needed. Verify thermal performance within the -25°C to +85°C operating temperature range.

ADCs/DACs - Special Purpose Part Context

The PCM1748 belongs to the PCM1748 family of high-performance audio DACs. It is designed for applications requiring low distortion and high dynamic range. The device integrates essential functions like the PLL and digital filters to simplify system design for stereo audio reproduction.

ADCs/DACs - Special Purpose Replacement Considerations

Check for direct pin-compatible substitutes within the PCM1748 family. Verify if other Texas Instruments audio DACs with similar 24-bit resolution and SPI interfaces meet the specific SNR and power requirements.
