PCM1725D

ADCs/DACs - Special Purpose Overview

The PCM1725D is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 16-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 +/- 5% FSR. The component is housed in a 14-pin SOIC package and is designed for operation within a temperature range of -25°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• 16-bit resolution with 96 kHz maximum sampling rate
• Stereo output with 97 dB SNR
• Serial interface compatibility
• Single 5V power supply operation

ADCs/DACs - Special Purpose Applications

• Audio systems requiring high-fidelity stereo conversion
• Professional audio equipment interfaces
• Consumer electronics with serial digital audio inputs

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-14 package variant. Confirm end-of-life status as indicated in distributor records, which may affect long-term availability. Ensure the design accommodates the specified 4.5 V to 5.5 V operating voltage range and industrial temperature limits.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 16-bit stereo DAC with serial interface is required. Compare against higher-resolution alternatives like the PCM1723 if 24-bit performance is needed. Verify that the SOIC-14 footprint matches the PCB layout constraints. Check if the 96 kHz limit meets the application's bandwidth requirements.

ADCs/DACs - Special Purpose Part Context

The PCM1725 belongs to the PCM17xx series of audio DACs from Texas Instruments. It serves as a mid-range solution offering 16-bit precision. It differs from the PCM1723, which offers 24-bit resolution, and the PCM1742, which supports 192 kHz sampling. The 'D' suffix specifically denotes the surface-mount SOIC package type.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in the provided data. Consider the PCM1723E for higher resolution or PCM1742KE for higher speed, noting differences in package and interface configuration.
