Description

The WM8751L is a low power, high quality stereo DAC with integrated headphone and loudspeaker amplifiers, designed to reduce external component requirements in portable digital audio applications.

The on-chip headphone amplifiers can deliver 40mW into a 16 load. Advanced on-chip digital signal processing performs bass and treble tone control.

The WM8751L can operate as a master or a slave, with various master clock frequencies including 12 or 24MHz for USB devices or standard 256fs rates like 12.288MHz and 24.576MHz. Different audio sample rates such as 96kHz, 48kHz, 44.1kHz are generated directly from the master clock without the need for an external PLL.

The WM8751L operates on supply voltages from 1.8V up to 3.6V, although the digital core can operate on a separate supply down to 1.42V, saving power. Different sections of the chip can also be powered down under software control.

The WM8751L is supplied in a very small and thin 5x5mm QFN package, ideal for use in hand-held and portable systems.
