PCM1723E/2K

ADCs/DACs - Special Purpose Overview

The PCM1723E/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 delta-sigma modulation architecture and includes a programmable phase-locked loop (PLL) for clock management. It operates on a single 5V supply, with voltage ranges from 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 94 dB and a gain error of +/- 3% full-scale range (FSR). The component is housed in an SSOP-24 package and communicates via a 3-wire serial interface.

• Single 5V analog and digital power supply operation

ADCs/DACs - Special Purpose Applications

• High-fidelity audio systems
• Professional audio equipment
• Home theater receivers

ADCs/DACs - Special Purpose Procurement Notes

The PCM1723E/2K is identified as an End-of-Life (EOL) product. Manufacturers have announced discontinuation, indicating that the component will become obsolete and production will cease. Designers should verify current availability through authorized distributors and consider long-term supply constraints when planning procurement strategies for existing or new projects.

ADCs/DACs - Special Purpose Selection Notes

This component is suitable for applications requiring high-resolution audio conversion with integrated clock recovery. The 94 dB SNR and 24-bit resolution support high-quality audio reproduction. Engineers must account for the 5V single-supply requirement and the SSOP-24 package dimensions during PCB layout. The inclusion of a programmable PLL makes it appropriate for systems needing flexible clock input handling.

ADCs/DACs - Special Purpose Part Context

The PCM1723E/2K belongs to the PCM1723 series of audio DACs from Texas Instruments. It is part of a family of components designed for stereo audio applications. The 'E' suffix typically denotes the operating temperature range, while '/2K' indicates the reel packaging quantity. This specific variant is a discontinued member of the broader audio IC portfolio.

ADCs/DACs - Special Purpose Replacement Considerations

Due to the EOL status, direct replacements may be limited. Potential alternatives within the same manufacturer's lineup include the PCM1740E/2K, which offers similar specifications but includes a VCXO. Other series members like the PCM1742E/2K provide higher sampling rates (192 kHz) but differ in interface type (SPI vs. 3-Wire Serial) and pinout compatibility.
