WM8986

Multimedia DAC With Class D Headphone and Line Out

DESCRIPTION

FEATURES

Stereo DAC:

The WM8986 is a low power, high quality, feature-rich stereo

DAC designed for portable multimedia applications that require

low power consumption and high quality audio.

•

DAC SNR 98dB, THD -86dB (‘A’ weighted @ 48kHz)

Headphone driver with ‘capless’ option

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

Class D headphone driver

Class AB headphone / line Driver

PSRR 70dB at 217Hz

The device integrates preamps for stereo differential mics, and

includes class D and class AB drivers for headphone and

differential or stereo line output. External component

requirements are reduced as no separate microphone or

headphone amplifiers are required.

•

Stereo, mono or differential line output

Mic Preamps:

Advanced DSP features include a 5-band equaliser and a digital

playback limiter. Highly flexible mixers enable many new

application features, with the option to playback any

combination of voice, line inputs and digital audio such as FM

Radio or MP3.

•

Stereo differential or mono microphone interfaces

Programmable preamp gain

Pseudo differential inputs with common mode rejection

Other Features:

The WM8986 digital audio interface can operate in master or

slave mode, while an integrated PLL provides flexible clocking

schemes.

•

Enhanced 3-D function for improved stereo separation

Digital playback limiter

5-band Equaliser

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

Low power, low voltage

2.5V to 3.6V analogue supplies

1.71V to 3.6V digital supplies

The WM8986 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. Additional power management control

enables individual sections of the chip to be powered down

under software control.

•

4x4mm 28-lead COL QFN package
