All-Digital High Efficiency
Power Amplifier
GENERAL DESCRIPTION
The DDX-2000 Controller and DDX-2060 Power
Device is an all-digital stereo amplifier chip set that
can provide up to 35 watts per channel of audio
power at very high efficiency. The DDX-2000
Controller includes two channels of DDX processing,
digital volume control, mute and special processing to
reduce distortion associated with signal clipping. The
controller accepts standard PCM serial formats and
operates from an external 256*Fs clock or from a
crystal. The DDX-2060 Power Device is a dual
channel Class-D H-Bridge power device that has a
logic interface, integrated bridge driver, high efficiency
MOSFET output transistors and protection circuitry.
The benefits of this system are the all-digital design
that eliminates the need for a digital to analog
converter (DAC) and the high efficiency operation
derived from the use of Apogee's patented damped
ternary pulse width modulation (PWM). This
approach provides an efficiency advantage over
conventional Class-D designs and up to three times
the efficiency of typical Class A/B amplifiers with
music input signals.
