PCM5102PW

ADCs/DACs - Special Purpose Overview

The PCM5102PW is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments, housed in a 20-pin TSSOP package. It supports I2S interface inputs with resolutions of 16, 24, and 32 bits, and sampling rates up to 384 kHz. Key electrical specifications include a signal-to-noise ratio (SNR) of 112 dB and a power supply voltage range of 3.3 V. The device operates within a temperature range of -25°C to +85°C and features two DAC output channels.

ADCs/DACs - Special Purpose Feature Summary

• Supports high-resolution audio with 16/24/32-bit data widths and sampling rates up to 384 kHz via I2S interface.
• Delivers high-fidelity performance with an SNR of 112 dB and low total harmonic distortion plus noise (THD+N).
• Integrated digital filter and delta-sigma modulation for efficient noise shaping and signal processing.
• Includes power-down and clock detection mechanisms to prevent pop noises during operation.

ADCs/DACs - Special Purpose Applications

• High-fidelity (Hi-Fi) audio playback systems.
• Embedded audio devices and wireless speakers.
• Smart home audio products requiring low-power stereo conversion.

ADCs/DACs - Special Purpose Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before procurement. Confirm that the TSSOP-20 package dimensions match the target PCB footprint. Ensure the design accounts for the specific 3.3V power supply requirements and I2S interface timing constraints defined in the official datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring stereo output with high dynamic range. Compare against PCM5101PWR if lower channel count or different packaging is needed. Consider the PCM5102AQPWRQ1 variant for automotive-grade requirements with extended temperature ranges (-40°C to +125°C) and AEC-Q100 qualification.

ADCs/DACs - Special Purpose Part Context

The PCM5102PW belongs to the PCM510x series of single-chip CMOS integrated circuits from Texas Instruments. This family includes the PCM5100, PCM5101, and PCM5102, offering varying levels of integration for stereo audio applications. The PW suffix specifically denotes the 20-pin Thin Shrink Small Outline Package (TSSOP).

ADCs/DACs - Special Purpose Replacement Considerations

The PCM5102AQPWRQ1 is a qualified automotive-grade alternative with extended temperature support. For non-automotive replacements, verify pin compatibility with other PCM510x variants, noting potential differences in operating temperature ranges and package availability.
