WM8959

Mobile Multimedia DAC with

Dual-Mode Class AB/D Speaker Driver

DESCRIPTION

FEATURES

•

DAC SNR 99dB (‘A’ weighted), THD -84dB at 48kHz, 3.3V

Stereo microphone interface

1W Speaker driver

The WM8959 is an ultra-low power hi-fi DAC designed for

multimedia handsets.

A powerful 1W speaker driver can operate in class D or AB

modes, providing total flexibility to the system designer. Low

leakage, high PSRR and pop/click suppression enable direct

battery connection for the speaker supply.

1W into 8Ω BTL speaker at <0.1% THD

80dB PSRR @ 217Hz

<1uA leakage with direct battery connection

Software-selectable class D or AB mode

Filterless connection supported

A flexible input configuration supports two microphone inputs

(single-ended or differential), a stereo line input, and a mono

differential line input.

•

Headphone / ear speaker drivers

40mW output power into 16Ω at 3.3V

Fully differential and capless modes supported

Four headphone drivers support fully differential headset drive,

providing excellent crosstalk performance and bass response,

maximising stereo effects, and allowing the removal of large

and expensive headphone capacitors. The headphone outputs

can also be configured to drive an ear speaker. A fully

differential path to these outputs direct from the input pins is

available to maximise signal quality and minimise power

consumption.

Low noise, lower power received voice path

•

Stereo or Mono differential line output

Pop/Click suppression

Powerful GPIO functions

Ultra-low power consumption

8.3mW analogue voice call

13.7mW DAC playback to headphones

•

On-chip PLL provides flexible clocking scheme

Sample rates: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48kHz

42-ball WCSP package (3.226x3.44x0.7mm, 0.5mm pitch)

Stereo 24-bit sigma-delta DACs provide hi-fi quality audio

playback, with a flexible digital audio interface supporting most

commonly-used clocking schemes. An integrated low power

PLL provides additional flexibility.

APPLICATIONS

•

Multimedia phones

GPS

The WM8959 is supplied in very small and thin 42-ball WCSP

package, ideal for portable systems.
