PCM5101APWR

ADCs/DACs - Special Purpose Overview

The PCM5101APWR is a stereo audio digital-to-analog converter (DAC) from Texas Instruments, housed in a 20-pin TSSOP package. It supports sampling rates up to 384 kHz and resolutions of 16, 24, or 32 bits. Key electrical specifications include a signal-to-noise ratio (SNR) of 106 dB and total harmonic distortion plus noise (THD+N) of 0.0022%. The device operates on a single supply voltage ranging from 3V to 3.6V and functions within an industrial temperature range of -25°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• DirectPath technology enables direct drive of headphones without external coupling capacitors
• Supports PCM interfaces with sampling frequencies up to 384 kHz
• Integrated 95dB RMS headphone amplifier for low-component-count designs

ADCs/DACs - Special Purpose Applications

• Portable audio players and media devices
• Smart home audio speakers
• Car infotainment systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'Not Recommended for New Designs' status indicated by some distributors before finalizing procurement plans. Confirm RoHS compliance details directly with the manufacturer documentation. Ensure the TSSOP-20 footprint matches the PCB layout requirements. Check for specific ordering suffixes if tape-and-reel quantities are required.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a compact stereo DAC with integrated headphone amplification is needed. It is suitable for applications requiring high SNR (106 dB) and low THD+N (0.0022%). Consider the 3V to 3.6V supply constraint and the -25°C to +85°C operating temperature range against system environmental conditions.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM5101A series of audio DACs. It shares functional similarities with the PCM5100 and PCM5102 but offers specific performance metrics like 106 dB SNR. The 'PWR' suffix denotes the TSSOP-20 surface-mount package variant manufactured by Texas Instruments.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM5101PWR is a pin-compatible alternative in the same family. Verify if the non-'A' suffix variant meets the specific performance requirements, noting potential differences in revision status or availability.
