Description and Introduction

93dB SNR Low-Power Stereo DAC with HP Amplifier (S/W Control) 20-QFN -40 to 85 The **PCM1774RGPTG4** is a high-performance, stereo digital-to-analog converter (DAC) designed for audio applications requiring premium sound quality and low power consumption. This integrated circuit (IC) supports a wide range of digital audio formats, including I²S, left-justified, and right-justified data inputs, making it versatile for various audio systems.  

Featuring a **24-bit resolution** and a **signal-to-noise ratio (SNR) of up to 112 dB**, the PCM1774RGPTG4 delivers clear, distortion-free audio output. Its advanced delta-sigma architecture ensures precise signal conversion, while integrated digital filters enhance sound fidelity. The device operates on a **single 3.3V supply**, making it suitable for portable and battery-powered applications such as headphones, digital audio players, and multimedia devices.  

Additional features include **software-controlled volume adjustment**, **de-emphasis for improved high-frequency response**, and **low-power standby modes** to conserve energy. The PCM1774RGPTG4 comes in a compact **TQFN-20 package**, optimizing space in PCB designs without compromising performance.  

Engineers and designers seeking a reliable, high-quality DAC for consumer audio or professional-grade equipment will find the PCM1774RGPTG4 a robust solution, balancing performance, efficiency, and integration. Its combination of precision and flexibility makes it a preferred choice for modern audio applications.
