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, low-power stereo digital-to-analog converter (DAC) designed for audio applications. This integrated circuit (IC) features a 24-bit resolution and supports sampling rates up to 192 kHz, ensuring high-fidelity sound reproduction for professional and consumer audio systems.  

With its advanced delta-sigma architecture, the PCM1774RGPTG4 delivers excellent signal-to-noise ratio (SNR) and total harmonic distortion (THD) performance, making it suitable for high-quality audio playback in devices such as home theater systems, soundbars, and portable media players. The device operates on a low supply voltage, optimizing power efficiency without compromising audio quality.  

The PCM1774RGPTG4 includes an integrated headphone amplifier, simplifying system design while providing direct output capability. Its flexible digital interface supports I2S, left-justified, and right-justified data formats, ensuring compatibility with a wide range of digital audio sources. Additionally, the IC features a power-down mode to minimize energy consumption when not in use.  

Packaged in a compact 20-pin TSSOP (RGP) form factor, the PCM1774RGPTG4 is ideal for space-constrained applications. Its robust design and superior audio performance make it a reliable choice for engineers seeking a high-quality DAC solution.
