Description and Introduction

24-Bit Low Power Stereo Audio DAC with Headphone Amplifier The **PCM1770RGAR** is a high-performance, low-power stereo digital-to-analog converter (DAC) designed for audio applications. This integrated circuit (IC) supports a wide range of input sample rates, making it suitable for various digital audio systems, including portable media players, home audio equipment, and automotive infotainment systems.  

Featuring a **24-bit resolution** and **96 kHz sampling rate**, the PCM1770RGAR delivers high-fidelity audio reproduction with minimal distortion. Its advanced architecture includes a **multi-bit delta-sigma modulator**, ensuring precise signal conversion while maintaining low power consumption. Additionally, the device integrates a **digital interpolation filter** and **analog output stage**, simplifying system design and reducing external component requirements.  

The PCM1770RGAR operates on a **single 3.3V supply**, making it ideal for battery-powered applications. It supports **I2S, left-justified, and right-justified** digital audio formats, offering flexibility in system integration. The IC also includes **soft mute and zero-detect functions**, enhancing user experience by minimizing unwanted noise during power transitions.  

Housed in a compact **VQFN-24 package**, the PCM1770RGAR is optimized for space-constrained designs while maintaining excellent thermal performance. Its combination of high audio quality, low power consumption, and versatile features makes it a reliable choice for modern digital audio systems.
