WM8983
Mobile Multimedia CODEC with 1W Speaker Driver
DESCRIPTION
The WM8983 is a low power, high quality stereo CODEC
designed for portable multimedia applications. Highly flexible
analogue mixing functions enable new application features,
combining hi-fi quality audio with voice communication.
The device integrates preamps for stereo differential mics,
and includes drivers for speaker, headphone and differential
or stereo line output. External component requirements are
reduced as no separate microphone or headphone amplifiers
are required.
Advanced on-chip digital signal processing includes a 5-band
equaliser, a mixed signal Automatic Level Control for the
microphone or line input through the ADC as well as a purely
digital limiter function for record or playback. A programmable
high pass filter in the ADC path is provided for wind noise
reduction and an IIR with programmable coefficients can be
used as a notch filter to suppress fixed-frequency noise.
The WM8983 digital audio interface can operate in master or
slave mode, while an integrated PLL supports flexible clocking
schemes. A-law and
-law
companding are fully supported.
The WM8983 operates at analogue supply voltages from 2.5V
to 3.3V, although the digital core can operate at voltages
down to 1.71V to save power. Speaker supplies can operate
up to 5V for increased speaker output power. Additional
power management control enables individual sections of the
chip to be powered down under software control.
