DESCRIPTION

· The WM8750L is a low-power, high-quality stereo CODEC designed for portable digital audio applications.
· It integrates interfaces for stereo/mono microphones and stereo headphones, reducing external component requirements.
· Features on-chip digital signal processing for graphic equalizer, 3-D sound enhancement, and automatic level control.
· Operates as master or slave with various master clock frequencies, supporting USB devices and standard 256fs rates.
· Generates audio sample rates directly from the master clock without an external PLL.
· Operates at supply voltages down to 1.8V, with a digital core capable of operating at 1.42V for power saving.
· Available in a compact 5x5mm QFN package, ideal for handheld and portable systems.
