PCM1808PW

ADCs/DACs - Special Purpose Overview

The PCM1808PW is a stereo audio analog-to-digital converter manufactured by Texas Instruments. It features two 24-bit delta-sigma modulators with a maximum sampling rate of 96 kHz. The device accepts single-ended analog voltage inputs with a peak-to-peak range of 3 V. It integrates a digital decimation filter providing 64x oversampling and an on-chip high-pass filter to remove DC components. Power consumption is specified at 62 mW, with power dissipation reaching 81 mW. The unit operates within a supply voltage range of 4.5 V to 5.5 V and functions in temperatures from -40°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 96 kHz sampling capability
• Single-ended analog input supporting 3 Vp-p signals
• Integrated 64x oversampling decimation filter
• On-chip high-pass filter for DC removal

ADCs/DACs - Special Purpose Applications

• Cost-sensitive consumer audio equipment
• Digital audio recording systems
• Professional audio interfaces requiring stereo ADC conversion

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type corresponds to TSSOP-14 when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the specific suffix matches the required tape-and-reel or cut-tape configuration for manufacturing integration.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring low-power stereo digitization with single-ended inputs. Verify that the system clock supports the required serial interface modes. Ensure the analog input signal does not exceed the 3 Vp-p limit to prevent clipping and maintain linearity.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1808 series of audio ADCs. It is functionally similar to the PCM1808PWR but utilizes a tube packaging format instead of reel packaging. The PCM1807 variant offers SPI interface compatibility, whereas this model uses a standard serial audio interface.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1808PWR serves as a direct functional substitute with identical electrical specifications, differing only in packaging format (tube versus reel). For automotive applications, the PCM1808QPWRQ1 provides AEC-Q100 qualification.
