DESCRIPTION
The WM8750L is a low power, high quality stereo CODEC
designed for portable digital audio applications.
The device integrates complete interfaces to stereo or mono
microphones and a stereo headphone. External component
requirements are drastically reduced as no separate
microphone
Advanced on-chip digital signal processing performs
graphic equaliser, 3-D sound enhancement and automatic
level control for the microphone or line input.
The WM8750L can operate as a master or a slave, with
various master clock frequencies including 12 or 24MHz for
USB devices, or standard 256f
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 WM8750L operates at supply voltages down to 1.8V,
although the digital core can operate at voltages down to
1.42V to save power, and the maximum for all supplies is
3.6 Volts. Different sections of the chip can also be powered
down under software control.
The WM8750L is supplied in a very small and thin 5x5mm
QFN package, ideal for use in hand-held and portable
systems.
