WM8980

Stereo CODEC With Speaker Driver and Video Buffer

DESCRIPTION

FEATURES

Stereo CODEC:

The WM8980 is a low power, high quality stereo CODEC with

integrated video buffer designed for portable applications such

as multimedia phone, digital still camera or digital camcorder.

•

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

ADC SNR 95dB, THD -80dB (‘A’ weighted @ 48kHz)

On-chip Headphone Driver with ‘capless’ option

The device integrates preamps for stereo differential mics, and

includes drivers for speakers, headphone and differential or

stereo line output. External component requirements are

reduced as no separate microphone or headphone amplifiers

are required.

40mW per channel into 16Ω / 3.3V SPKVDD

•

0.9W output power into 8Ω BTL speaker / 5V SPKVDD

Capable of driving piezo speakers

Stereo speaker drive configuration

Mic Preamps:

•

Stereo Differential or mono microphone Interfaces

An integrated video buffer is provided which has programmable

gain from 0-6dB (6-12dB unloaded), sync-tip clamp and a 3^rd

order input low pass filter for signal re-construction.

Programmable preamp gain

Psuedo differential inputs with common mode rejection

Programmable ALC / Noise Gate in ADC path

Advanced on-chip digital signal processing includes a 5-band

•

Low-noise bias supplied for electret microphones

equaliser, a mixed signal Automatic Level Control for the Other Features:

microphone or line input through the ADC as well as a purely

digital limiter function for record or playback. Additional digital

filtering options are available in the ADC path, to cater for

application filtering such as ‘wind noise reduction’.

•

Integrated video buffer with LPF filter and clamp.

Enhanced 3-D function for improved stereo separation

Digital playback limiter

5-band Equaliser (record or playback)

Programmable ADC High Pass Filter (wind noise reduction)

Programmable ADC Notch Filter

Aux inputs for stereo analog input signals or ‘beep’

On-chip PLL supporting 12, 13, 19.2MHz and other clocks

Support for 8, 11.025, 12, 16, 22.05, 24, 32, 44.1 and

48kHz sample rates

The WM8980 digital audio interface can operate as a master or

a slave. An internal PLL can generate all required audio clocks

for the CODEC from common reference clock frequencies, such

as 12MHz and 13MHz.

The WM8980 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. The speaker outputs and OUT3/4 line

outputs can run from a 5V supply if increased output power is

required. Individual sections of the chip can also be powered

down under software control.

•

Low power, low voltage

2.5V to 3.6V (digital: 1.71V to 3.6V)

6x6mm 40-lead QFN package

APPLICATIONS

•

Stereo Camcorder or DSC

Multimedia Phone
