Description and Introduction

24-Bit 192 kHz Sampling Advanced Segment Audio Stereo DAC The **PCM1738E** is a high-performance, 24-bit digital-to-analog converter (DAC) designed for precision audio applications. As part of the Burr-Brown product line, it delivers exceptional signal clarity and low distortion, making it ideal for professional audio equipment, digital mixing consoles, and high-end consumer audio systems.  

Featuring a **multibit Delta-Sigma architecture**, the PCM1738E ensures accurate signal reproduction with minimal noise and jitter. It supports sampling rates up to **192 kHz**, providing high-resolution audio output. The device incorporates an **8× digital interpolation filter**, reducing the need for external filtering components while maintaining signal integrity.  

The PCM1738E operates on a **single +5V supply**, simplifying system design and power management. It includes advanced features such as **soft mute, digital attenuation, and de-emphasis control**, enhancing flexibility in various audio processing scenarios. Additionally, its **serial interface** allows seamless integration with digital signal processors (DSPs) and microcontrollers.  

Engineers favor the PCM1738E for its **low total harmonic distortion (THD) and high dynamic range**, ensuring faithful audio reproduction. Whether used in studio-grade equipment or premium home audio systems, this DAC remains a reliable choice for demanding audio applications.
