DESCRIPTION
The WM8973L 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 or headphone amplifiers are required.
Advanced on-chip digital signal processing performs graphic equaliser, 3-D
sound enhancement and automatic level control for the microphone or line
input.
The WM8973L 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 WM8973L 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 WM8973L is supplied in a very small and thin 5x5mm QFN package, ideal for
use in hand-held and portable systems.
