Technical Specifications:

The WM8758BGEFL/R supports sample rates ranging from 8 kHz to 192 kHz. It offers a high signal-to-noise ratio (SNR) and low total harmonic distortion plus noise (THD+N), ensuring high-fidelity audio output. The integrated headphone amplifier is designed to drive headphones with a typical impedance range of 16-32 ohms. The device operates on a low supply voltage, typically 1.8V for digital circuitry and 3.3V for analog components, minimizing power consumption. Communication and configuration are achieved through an I2C interface. The QFN package provides excellent thermal performance and allows for compact PCB layouts.

The '/R' suffix usually indicates that the component is supplied on tape and reel, making it suitable for automated assembly processes.
