PCM1728E

ADCs/DACs - Special Purpose Overview

The PCM1728E is a stereo audio digital-to-analog converter (DAC) from Texas Instruments' SoundPlus series. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device utilizes an I2S digital interface for data input. It operates on a single 5V supply voltage for both analog and digital sections. The component is housed in a 20-lead SSOP package with a width of 5.30 mm. Designed for surface-mount installation, it functions within a temperature range of -25°C to 85°C. This part is classified as obsolete status.

ADCs/DACs - Special Purpose Procurement Notes

The PCM1728E has reached end-of-life status and is no longer actively manufactured by Texas Instruments. Availability is limited to existing stock held by distributors or third-party suppliers such as Rochester Electronics. Verification of authenticity and lot traceability is critical when sourcing from non-OEM channels due to the discontinued nature of the component.

ADCs/DACs - Special Purpose Selection Notes

Engineers requiring a direct replacement should consider newer members of the PCM17xx family or alternative high-performance audio DACs from current TI portfolios. Design-in efforts must account for the obsolescence of the PCM1728E. Alternative components may require schematic modifications and PCB layout adjustments to match pin configurations and electrical specifications.

ADCs/DACs - Special Purpose Part Context

The PCM1728E belongs to the SoundPlus series of audio data converters. It shares architectural similarities with other devices in the PCM172x family, such as the PCM1720E and PCM1727E, which also offer 24-bit resolution and I2S interfaces. These components target similar high-fidelity audio applications but differ in channel counts and package options.

ADCs/DACs - Special Purpose Replacement Considerations

No specific public substitute part numbers are confirmed for direct pin-to-pin replacement. Review the PCM179x or PCM17xx series datasheets for potential modern equivalents that meet similar performance criteria.
