Description and Introduction

105dB SNR 8-Channel Audio DAC with TDM Mode 28-HTSSOP -40 to 85 The PCM1681PWPRG4 is a high-performance, 24-bit digital-to-analog converter (DAC) designed for precision audio applications. This integrated circuit (IC) features an advanced architecture that ensures low distortion and high signal-to-noise ratio (SNR), making it suitable for professional audio equipment, home theater systems, and high-fidelity sound reproduction.  

Operating with a wide supply voltage range, the PCM1681PWPRG4 supports sampling rates up to 192 kHz, delivering exceptional audio clarity and detail. Its multi-bit delta-sigma modulation minimizes noise while maintaining linearity across the entire frequency spectrum. The device also includes integrated digital filters, simplifying system design and reducing external component requirements.  

Housed in a TSSOP-28 package, the PCM1681PWPRG4 offers a compact footprint, making it ideal for space-constrained applications. It supports both I2S and left-justified audio data formats, ensuring compatibility with a variety of digital signal sources. Additionally, its low power consumption enhances energy efficiency without compromising performance.  

Engineers and designers seeking a reliable, high-resolution DAC for premium audio solutions will find the PCM1681PWPRG4 to be a robust and versatile choice, combining technical excellence with ease of integration.
