PCM2900BDB

Codecs Overview

The PCM2900BDB is a stereo audio codec manufactured by Texas Instruments, designed for USB interface applications. It integrates single-ended analog input and output capabilities alongside an S/PDIF digital audio interface. The device operates within a supply voltage range of 3.0 V to 5.5 V and supports sampling rates from 8 kHz to 48 kHz. It features a 16-bit resolution with two DACs and one ADC. The component is housed in a 28-pin SSOP package and functions across a temperature range of -25°C to +85°C.

Codecs Feature Summary

• Integrates a full-duplex USB 1.1 interface for direct connection to host systems without external transceivers.
• Includes dedicated S/PDIF transmitter and receiver circuits for digital audio connectivity.
• Provides integrated single-ended analog line inputs and outputs with built-in programmable gain amplifiers.

Codecs Applications

• USB-based audio peripherals such as external sound cards and audio adapters.
• Digital audio workstations requiring simultaneous analog and digital I/O.
• Consumer electronics integrating high-fidelity stereo recording and playback.

Codecs Procurement Notes

Verify the specific suffix 'BDB' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure that the required operating voltage and temperature range align with the system design specifications before procurement.

Codecs Selection Notes

Select this component when a complete solution combining USB connectivity, S/PDIF handling, and analog conversion is required. Compare performance metrics such as signal-to-noise ratio and total harmonic distortion against alternative codecs if higher fidelity or different interface standards are necessary.

Codecs Part Context

This part belongs to the PCM2900 series of stereo audio codecs. It serves as a foundational component for designs needing integrated USB and digital audio processing. The 'BDB' designation typically indicates a specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Codecs Replacement Considerations

The PCM2900CDBR is a documented successor within the same family, offering updated specifications. Verify pin compatibility and software driver support when transitioning from the PCM2900BDB to newer variants in the PCM290x series.
