Description and Introduction

105dB SNR 8-Channel Audio DAC with TDM Mode The **PCM1681** is a high-performance, 24-bit digital-to-analog converter (DAC) designed for audio applications requiring exceptional sound quality and precision. This integrated circuit (IC) supports sampling rates up to **192 kHz**, making it suitable for high-resolution audio systems, including home theater setups, professional audio equipment, and digital music players.  

Featuring a **multi-bit delta-sigma architecture**, the PCM1681 minimizes distortion and noise, delivering clear and accurate audio reproduction. It accepts **I2S, left-justified, and right-justified** digital input formats, ensuring compatibility with a wide range of digital audio sources. Additionally, its **on-chip digital filter** enhances signal integrity by reducing unwanted artifacts.  

The device operates on a **single 5V supply**, simplifying system integration while maintaining low power consumption. Its **compact package** and robust design make it an excellent choice for space-constrained applications without compromising performance.  

Engineers and designers favor the PCM1681 for its **reliability, ease of use, and superior audio performance**, making it a preferred solution for high-fidelity audio systems. Whether used in consumer electronics or professional audio equipment, this DAC ensures a premium listening experience.

Application Scenarios & Design Considerations

105dB SNR 8-Channel Audio DAC with TDM Mode

Alternative Part Number

  • CS4382A --: Pin-compatible 24-bit 192 kHz 8-channel audio DAC with similar serial audio interface, widely used as a drop-in replacement for the PCM1681 in multichannel audio designs.
  • AK4458 --: 8-channel 32-bit audio DAC with comparable I2S/TDM inputs and supply range, offering higher resolution and a similar application footprint for replacing the PCM1681.
  • AD1955 --: High-performance multibit sigma-delta audio DAC with similar audio interface and analog output characteristics, suitable as a functional alternative when the PCM1681 is unavailable.
