PCM2906DBR

Codecs Overview

The PCM2906DBR is a stereo USB audio codec manufactured by Texas Instruments. It integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs) with 16-bit resolution. The device operates on a single 5 V power supply and supports sample rates up to 48 kHz. It features S/PDIF I/O capabilities and includes a 500 mA maximum power configuration for external loads. The component is housed in a 28-pin SSOP package designed for surface mount technology, operating within a temperature range of -25°C to +85°C.

Codecs Feature Summary

• Integrates stereo USB connectivity with built-in ADC and DAC channels
• Supports S/PDIF input and output interfaces for digital audio transmission
• Includes high-current capability with 500 mA maximum power configuration

Codecs Applications

• USB audio peripherals requiring stereo input and output
• Digital audio systems utilizing S/PDIF interface standards
• Embedded audio subsystems with limited power supply constraints

Codecs Procurement Notes

Verify the specific suffix 'DBR' against official Texas Instruments documentation to confirm the tape and reel packaging format and pinout compatibility. Ensure the procurement source provides valid RoHS compliance data and original manufacturer traceability. Cross-reference the part number with current datasheets to validate active status and any recent design changes or obsolescence notices before finalizing orders.

Codecs Selection Notes

Select this component when a stereo USB audio solution with integrated S/PDIF support is required. The fixed 5 V supply requirement and 16-bit resolution define its performance envelope. Compare against similar models like the PCM2903CDBR if different voltage levels or alternative packaging options are necessary for the target application design.

Codecs Part Context

This part belongs to the PCM2906C series of stereo USB audio codecs from Texas Instruments. It is functionally related to other members of the family such as the PCM2903C, which shares similar audio conversion capabilities but may differ in specific interface configurations or packaging types. The series targets compact audio applications requiring direct USB integration.

Codecs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference material. Verify compatibility with legacy designs using the PCM2903CDBR only after confirming pinout and functional equivalence through official engineering change notices.
