WM8758B

Stereo CODEC with Headphone Driver and Line Out

DESCRIPTION

FEATURES

Stereo CODEC:

The WM8758B is a low power, high quality stereo CODEC

designed for portable applications such as MP3 audio player.

•

DAC SNR 100dB, THD -86dB (‘A’ weighted @ 48kHz)

ADC SNR 92.5dB, THD -75dB (‘A’ weighted @ 48kHz)

Headphone Driver

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

Line output

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.

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. Additional digital

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

application filtering such as ‘wind noise reduction’ and notch

filter.

Other Features:

•

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

PLL supporting various clocks between 8MHz-50MHz

Sample rates supported (kHz): 8, 11.025, 12, 16, 22.05, 24,

32, 44.1, 48

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.

•

Low power, low voltage

2.5V to 3.6V analogue supplies

1.71V to 3.6V digital supplies

5x5mm 32-lead QFN package
