PCM5102PWR

ADCs/DACs - Special Purpose Overview

The PCM5102PWR is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It utilizes a 32-bit, 384kHz delta-sigma modulation architecture to convert digital audio data into analog signals. The device features a DirectPath output stage that eliminates the need for external coupling capacitors. Key electrical specifications include a signal-to-noise ratio (SNR) of 112 dB and a total harmonic distortion plus noise (THD+N) of -93 dB. It operates on a single 3.3V supply and supports I2S, left-justified, and right-justified digital audio interfaces.

ADCs/DACs - Special Purpose Feature Summary

• 32-bit resolution with sampling rates up to 384 kHz
• Integrated DirectPath output stage for capacitor-free connections
• High performance metrics: 112 dB SNR and -93 dB THD+N
• Supports I2S, Left-Justified, and Right-Justified digital audio formats

ADCs/DACs - Special Purpose Applications

• Portable media players and smartphones
• Bluetooth audio receivers and wireless speakers
• Home theater systems and AV receivers
• Embedded audio processing modules

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PWR' confirms the tape-and-reel packaging format distinct from tube-packaged variants like 'PW'. Confirm current production status as some PCM510x series components may be marked Not Recommended for New Design (NRND). Ensure compatibility with 3.3V logic levels for the digital interface.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a high-fidelity stereo DAC with integrated output drivers is required without external coupling capacitors. It is suitable for designs needing support for high-resolution audio up to 384kHz. Compare against PCM5100 or PCM5101 if different pinouts or specific automotive qualifications are not needed.

ADCs/DACs - Special Purpose Part Context

The PCM5102PWR belongs to the PCM510xA family of audio DACs from Texas Instruments. This family is designed for consumer audio applications requiring high dynamic range and low power consumption. The PWR suffix indicates a 20-pin TSSOP package in a tape-and-reel configuration for automated surface-mount assembly.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM5102APWR is an upgraded version within the same family offering improved specifications. The PCM5101PWR is a related part but may have different feature sets or qualification statuses. Verify pinout compatibility before substituting.
