Description and Introduction

120dB SNR Stereo DAC with BiCMOS Advanced Sign Magnitude Architecture 20-SO The **PCM1702U/2KE6** is a high-performance, 20-bit digital-to-analog converter (DAC) designed for precision audio applications. Manufactured by Burr-Brown (now part of Texas Instruments), this component is widely recognized for its exceptional linearity, low distortion, and superior sound quality, making it a preferred choice in high-end audio systems.  

Featuring a **multi-bit delta-sigma architecture**, the PCM1702U/2KE6 delivers accurate signal conversion with minimal noise and jitter. Its **20-bit resolution** ensures detailed audio reproduction, while its **±2 LSB integral nonlinearity (INL)** and **±1 LSB differential nonlinearity (DNL)** guarantee high accuracy. The device operates with a **5V power supply** and supports sampling rates up to **96 kHz**, catering to professional and audiophile-grade applications.  

The PCM1702U/2KE6 is housed in a **SOIC-28 package**, offering compact integration for PCB designs. Its robust performance and reliability have made it a staple in CD players, digital audio workstations, and premium DAC modules.  

Engineers and audio enthusiasts value this DAC for its **low glitch energy** and **excellent dynamic range**, ensuring faithful audio reproduction. While newer DACs have emerged, the PCM1702U/2KE6 remains a benchmark for high-fidelity digital-to-analog conversion.
