DESCRIPTION

The WM8758B is a low power, high quality stereo CODEC

designed for portable applications such as MP3 audio player.

The device integrates preamps for stereo differential mics, and

drivers for headphone and differential or stereo line output.

External component requirements are reduced as no separate

microphone or headphone amplifiers are required. Headphone

and line common feedback improves crosstalk and noise

performance.

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. Additional digital

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

application filtering such as ‘wind noise reduction’ and notch

filter.

The WM8758B digital audio interface can operate in master or

slave mode with an integrated PLL.

The WM8758B operates at analogue supply voltages from 2.5V

to 3.3V, although the digital supply voltages can operate at

voltages down to 1.71V to save power. Additional power

management control enables individual sections of the chip to

be powered down under software control.
