Description and Introduction

Stereo Audio Codec with USB Interface and Single-ended Input/Output The **PCM2901E/2K** is a highly integrated **USB audio codec** designed for high-quality digital audio applications. This component combines a **USB 2.0 full-speed controller**, a **stereo digital-to-analog converter (DAC)**, and an **analog-to-digital converter (ADC)** in a single package, making it ideal for compact and power-efficient designs.  

Supporting **16-bit resolution** and **sample rates up to 48 kHz**, the PCM2901E/2K ensures clear audio playback and recording. Its plug-and-play compatibility with standard **USB audio class drivers** simplifies integration, eliminating the need for additional firmware development. The device also features **on-chip clock generation**, reducing external component requirements.  

With built-in **headphone amplification** and **analog volume control**, the PCM2901E/2K is well-suited for applications such as **USB headsets, audio interfaces, and portable recording devices**. Its low power consumption and small footprint enhance its appeal for consumer electronics and embedded systems.  

Engineers appreciate the PCM2901E/2K for its reliability, ease of implementation, and robust performance, making it a preferred choice for cost-effective USB audio solutions. Whether for professional or consumer use, this component delivers a seamless audio experience with minimal design complexity.

Application Scenarios & Design Considerations

Stereo Audio Codec with USB Interface and Single-ended Input/Output

Alternative Part Number

  • CM108AH --: USB audio codec with built-in ADC/DAC and S/PDIF support, functionally similar to the PCM2901 for USB audio applications.
  • SA9023A --: USB audio bridge/codec IC offering comparable USB-to-analog audio conversion, suitable as a functional substitute.
  • PCM2900C --: Same TI PCM290x family USB audio codec with similar feature set; different series suffix makes it a distinguishable drop-in style alternative.
