PCM1718EG4

ADCs/DACs - Special Purpose Overview

The PCM1718EG4 is a stereo digital-to-analog converter (DAC) from Texas Instruments, part of the SoundPlus family. It features a 20-bit DAC core with delta-sigma modulation to achieve high audio performance metrics, including a typical signal-to-noise ratio (SNR) of 100 dB and a dynamic range of 96 dB. The device operates on a single 5 V supply and supports sampling rates up to 96 kHz. It utilizes a serial interface compatible with standard audio protocols such as I²S, DSP, and left-justified formats. The component is housed in a 16-pin TSSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 20-bit delta-sigma DAC core providing 100 dB SNR and 96 dB dynamic range
• Supports sampling frequencies up to 96 kHz with flexible serial audio interfaces
• On-chip digital volume control with 0.5 dB step resolution over a -94.5 dB to 0 dB range
• Single 5 V power supply operation with integrated reference voltage

ADCs/DACs - Special Purpose Applications

• Compact audio systems requiring low power consumption
• Portable CD players and portable media devices
• Miniature home theater and surround sound processors
• Professional audio equipment with space constraints

ADCs/DACs - Special Purpose Part Context

The PCM1718EG4 is the lead-free, RoHS-compliant version of the PCM1718. The 'G4' suffix indicates compliance with environmental standards, specifically regarding lead content and packaging materials, while maintaining identical electrical and functional specifications to the standard PCM1718 model.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1718 serves as the direct non-RoHS equivalent. For pin-compatible upgrades within the same family, the PCM1716 offers similar functionality with potentially different interface or power characteristics.
