PCM1710U/1K

ADCs/DACs - Special Purpose Overview

The PCM1710U is a stereo audio digital-to-analog converter from Texas Instruments, housed in a 28-pin SOIC package. It integrates an 8x oversampling digital filter, a multi-level delta-sigma DAC, and an analog low-pass output amplifier. The device accepts 16-bit or 20-bit input data formats with system clocks of 256fs or 384fs. Key performance metrics include a signal-to-noise ratio of 110 dB, dynamic range of 98 dB, and THD+N of -92 dB. It operates on a single +5V power supply within a temperature range of -25°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Complete stereo DAC with integrated 8x oversampling digital interpolation filter and analog voltage output stage
• High-performance specifications including 110 dB SNR, 98 dB dynamic range, and -92 dB THD+N
• On-chip digital features: soft mute, digital attenuation, de-emphasis, and double-speed dubbing mode
• Flexible input interface accepting 16/20-bit normal format or 16-bit IIS data with selectable serial or parallel control modes

ADCs/DACs - Special Purpose Applications

• Audiobook players and portable media devices
• Bookshelf CD players and automotive CD systems
• MIDI synthesizers and electronic keyboards
• Set-top boxes and CD-ROM drives
• CD-Interactive and CD-Karaoke systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the component revision and date code against current inventory requirements. Confirm that the 28-pin SOIC footprint matches the design layout. Ensure the application circuit provides adequate bypassing for the +5V supplies as specified in the datasheet to maintain optimal noise performance.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single-supply +5V operation is required for stereo audio conversion. It is suitable for applications needing high dynamic range (98 dB) without external DAC components. Consider the 28-pin SOIC package size constraints and verify compatibility with 16-bit or 20-bit digital audio interfaces.

ADCs/DACs - Special Purpose Part Context

The PCM1710U belongs to the Burr-Brown/Texas Instruments PCM17xx series of audio DACs. It is designed for consumer electronics requiring high fidelity in a compact form factor. The device replaces older discrete DAC solutions by integrating the filter, modulator, and output amplifier into a single IC.
