Mobile Multimedia CODEC with 1W Speaker Driver

DESCRIPTION

FEATURES

Stereo Codec:

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.

•

DAC SNR 98dB, THD -84dB (‘A’ weighted @ 48kHz)

ADC SNR 95dB, THD -84dB (‘A’ weighted @ 48kHz)

Speaker driver (1W into 8Ω BTL with 5V supply)

Headphone driver with ‘capless’ option

40mW per channel output power into 16Ω / 3.3V AVDD2

Pop and click suppression

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.

Mic Preamps:

•

Stereo Differential or mono microphone Interfaces

Programmable preamp gain

Psuedo differential inputs with common mode rejection

Programmable ALC / Noise Gate in ADC path

Low-noise bias supplied for electret microphones

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.

Other Features:

•

Enhanced 3-D function for improved stereo separation

Highly flexible mixing functions

5-band equaliser (ADC or DAC path)

ADC Programmable high pass filter (wind noise reduction)

ADC Programmable IIR notch filter

Aux inputs for stereo analog input signals or ‘beep’

PLL supporting various clocks between 8MHz-50MHz

Sample rates supported (kHz): 8, 11.025, 16, 12, 16, 22.05,

24, 32, 44.1, 48

The WM8983 digital audio interface can operate in master or

slave mode, while an integrated PLL supports flexible clocking

schemes. A-law and µ-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.

•

2.5V to 3.6V analogue supplies

1.71V to 3.6V digital supplies

2.5V to 5.5V speaker supplies

5x5mm 32-pin QFN package
