PCM1808PWR

ADCs/DACs - Special Purpose Overview

The PCM1808PWR is a stereo analog-to-digital converter manufactured by Texas Instruments, housed in a 14-pin TSSOP package. It features two 24-bit delta-sigma converters with single-ended voltage inputs capable of handling up to 3 Vp-p. The device supports sampling rates up to 96 kHz and utilizes a serial audio interface compatible with standard PCM formats. Operating on a 5-V analog supply and a 3.3-V digital supply, it consumes approximately 62 mW of power. Key performance metrics include a typical signal-to-noise ratio of 99 dB and total harmonic distortion plus noise of -93 dB.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 96 kHz maximum sampling rate
• Single-ended analog input range of 3 Vp-p
• Integrated oversampling decimation filter with x64 oversampling
• On-chip high-pass filter for DC removal

ADCs/DACs - Special Purpose Applications

• Consumer audio equipment requiring low-cost stereo digitization
• Digital audio processing systems using I2S interfaces
• Portable devices utilizing mixed 5-V and 3.3-V power domains

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix PWR indicates tape-and-reel packaging within the TSSOP-14 form factor. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for automotive or industrial qualification if required by the specific design constraints.

ADCs/DACs - Special Purpose Selection Notes

Select this component when single-ended inputs are preferred over differential architectures to simplify front-end circuitry. The fixed 3 Vp-p input limit requires careful gain staging to prevent clipping. Verify that the host processor supports the required serial clock and bit-clock configurations for the chosen data format.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1808 family of audio ADCs. Variants such as PCM1808PWG4 denote lead-free and RoHS-compliant versions of the same functional device. Automotive-grade equivalents like the PCM1808QPWRQ1 offer extended temperature ranges and AEC-Q100 certification while maintaining similar core specifications.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible substitutes include the PCM1807 series, though interface protocols may differ. For automotive applications, consider the PCM1808QPWRQ1 for enhanced thermal stability. Always validate electrical parameters against the specific revision datasheet before substitution.
