WM8602

2.1 Channel PWM Controller

DESCRIPTION

FEATURES

•

Multi-channel PWM audio amplifier controller

Supports Stereo input

The WM8602 comprises a high performance stereo + sub

PWM digital power amplifier controller. Simply by adding

appropriate power output stages a 2.1 channel power

amplifier may be built. Two identical full audio bandwidth

Supports stereo or 2.1 with sub channel generation

PWM Audio Performance with typical output stage

channels, plus

a reduced bandwidth sub channel are

−

100dB SNR (‘A’ weighted @ 48kHz)

0.01% THD @ 1Watt

provided as PWM outputs.

The PCM to PWM converter supports up to 2 channels of

audio, in PCM input formats. The on board bass

management enables the generation of a sub channel from

the stereo PCM data.

0.1% THD @ 30Watt

•

Integrated Bass Management support with adjustable filter

Integrated 4-band Graphic Equaliser

Adjustable output stage filter compensation for different

speakers

A Graphic Equaliser function is provided, plus selectable

high frequency equalisation to suit different speaker types.

Independent volume control for each channel is provided.

•

Volume control on each channel +24dB to -103.5dB in

0.5dB steps, with volume ramping and auto-mute

functions

The WM8602 PWM controller is compatible with integrated

switching output stages available from a number of vendors

or alternatively may be used with a discrete output stage

configuration and achieve similar levels of performance.

•

Programmable Dynamic Peak Compressor avoids clipping

even at high volume settings

Internal PLL and optional crystal oscillator, supporting

Audio and MPEG standards

A Dynamic Peak Compressor with programmable attack

and decay times is included, which allows headroom for

tone control, bass management and extra digital gain to be

provided, without clipping occurring.

•

2/3-Wire MPU Serial Control Interface

Master or Slave Clocking Mode

Programmable Audio Data Interface Modes

I²S, Left, Right Justified or DSP

A Synchroniser allows slaving to LRCLK, thus making the

WM8602 independent of source MCLK frequency and jitter.

−

16/20/24/32 bit Word Lengths

•

De-emphasis support for stereo

CMOS digital outputs

The device is controlled via a 2/3 wire serial interface. The

interface provides access to all features including channel

selection, volume controls, mutes, de-emphasis and power

management facilities. The device is supplied in a 28-pin

SSOP package.

APPLICATIONS

•

Hi-Fi systems

Automotive Audio

Boombox

Active Speakers
