PCM1771PW

ADCs/DACs - Special Purpose Overview

The PCM1771PW is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 50 kHz. The device operates on a single power supply ranging from 1.6 V to 3.6 V, with a typical operating current of 2.5 mA. It utilizes an I2S serial interface for data input. Key performance metrics include a signal-to-noise ratio (SNR) of 98 dB and a total harmonic distortion plus noise (THD+N) of 0.007%. The component is housed in a 16-pin TSSOP package.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 98 dB SNR
• Low power consumption at 2.5 mA
• I2S digital interface compatibility
• Single-supply operation (1.6 V to 3.6 V)

ADCs/DACs - Special Purpose Applications

• Portable audio players
• Mobile communication devices
• Compact audio systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the design supports the required I2S protocol timing specifications.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-fidelity audio conversion with strict power constraints. Compare against the PCM1771RGA if a smaller VQFNP-20 package is preferred, noting the interface difference between I2S and 3-Wire Serial. Verify that the 50 kHz maximum sampling rate meets the system's audio bandwidth requirements.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1771 series of low-power stereo DACs. It shares core audio performance characteristics with the PCM1770 but differs in interface type and packaging options within the family. The PW suffix specifically denotes the surface-mount TSSOP package configuration.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1771PWR is a tape-and-reel version of the same functional device. The PCM1771RGA offers a different package and serial interface. Direct pin-compatible replacements are not explicitly documented in the provided source material.
