PCM1710U/1KG4

ADCs/DACs - Special Purpose Overview

The PCM1710U/1KG4 is a stereo audio digital-to-analog converter (DAC) from Texas Instruments, housed in a 28-pin SOIC package. It integrates an 8x oversampling digital filter, a multi-level delta-sigma DAC, an analog low-pass filter, and output amplifiers. The device accepts 16-bit or 20-bit input data formats with a single +5V power supply. Key performance metrics include a signal-to-noise ratio of 110 dB, dynamic range of 98 dB, and THD+N of -92 dB at full scale. It supports system clocks of 256fs or 384fs and operates 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 4th-order multi-level delta-sigma modulator.
• Accepts 16-bit or 20-bit input data in Normal (MSB first, right justified) or IIS formats.
• On-chip digital features include soft mute, digital attenuation, de-emphasis, and double-speed dubbing mode.
• Single +5V power supply operation with separate analog and digital power domains.

ADCs/DACs - Special Purpose Applications

• Automotive CD players
• Bookshelf CD players and tuners
• MIDI applications and keyboards
• Set-top boxes and CD-ROM drives
• CD-Interactive and CD-Karaoke systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the component matches the specific PCM1710U/1KG4 designation. Confirm the package type is 28-pin SOIC and that the device meets the required operating temperature range of -25°C to +85°C. Ensure the supplier provides documentation confirming the single +5V power supply requirement and serial/parallel interface compatibility.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring a complete stereo DAC solution with high dynamic range and low distortion. It is suitable for designs constrained by a single +5V supply. Consider the 22.625/fs delay time for professional broadcast applications where latency is critical. Verify that the host controller can support the required 256fs or 384fs system clock frequencies for the desired sampling rates.

ADCs/DACs - Special Purpose Part Context

The PCM1710U/1KG4 belongs to the PCM1710 series of stereo audio DACs manufactured by Texas Instruments. It is designed as a cost-effective, small-footprint solution for consumer audio electronics. The 'U' suffix indicates the 28-pin SOIC package, while '/1KG4' typically denotes specific packaging or reel configuration details provided by the manufacturer.
