PCM1808QPWRQ1

ADCs/DACs - Special Purpose Overview

The PCM1808QPWRQ1 is a single-ended, analog-input stereo audio analog-to-digital converter (ADC) from Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device utilizes a delta-sigma architecture with an oversampling decimation filter operating at x64. Key performance metrics include a typical total harmonic distortion plus noise (THD+N) of -93 dB, a signal-to-noise ratio (SNR) of 99 dB, and a dynamic range of 99 dB. It operates within a supply voltage range of 4.5 V to 5.5 V and functions across an extended temperature range of -40°C to +125°C. The component is housed in a TSSOP-14 package.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit stereo delta-sigma ADC with 96 kHz maximum sampling rate
• High-performance audio specifications: 99 dB SNR and -93 dB THD+N
• On-chip high-pass filter with a cutoff frequency of 0.91 Hz at 48 kHz sampling rate
• AEC-Q100 qualified for automotive applications

ADCs/DACs - Special Purpose Applications

• Automotive audio systems requiring AEC-Q100 compliance
• Digital audio interfaces using flexible PCM protocols
• Single-ended analog input signal digitization

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PWRQ1' confirms the TSSOP-14 package and automotive qualification status. Confirm RoHS compliance details through the manufacturer's official documentation. Ensure the design supports the required 4.5 V to 5.5 V power supply range and serial interface timing constraints.

ADCs/DACs - Special Purpose Selection Notes

Select this component when single-ended analog inputs are required rather than differential configurations. It is suitable for designs needing automotive reliability certification (-40°C to +125°C). Compare against PCM1808 variants if industrial or commercial temperature ranges suffice, as those may offer different packaging or pricing structures.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1808-Q1 series, which extends the standard PCM1808 family for automotive use. It shares core electrical characteristics with the non-automotive PCM1808 but adheres to AEC-Q100 standards. Related parts in the series include the PCM1808PWR and PCM1808PWG4.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1808PWR serves as the commercial-grade equivalent with identical electrical specifications but lacks automotive qualification. Verify that the target application does not strictly require AEC-Q100 certification before substituting.
