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
channels, plus a reduced bandwidth sub channel are
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.
A Graphic Equaliser function is provided, plus selectable
high frequency equalisation to suit different speaker types.
Independent volume control for each channel is provided.
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.
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.
A Synchroniser allows slaving to LRCLK, thus making the
WM8602 independent of source MCLK frequency and jitter.
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.
