DDX-2000/2060

All-Digital High Efficiency

Power Amplifier

GENERAL DESCRIPTION

FEATURES

HIGH OUTPUT CAPABILITY

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

2x35W into 8 W @ <1% THD+N

1x70W into 4 W @ <1% THD+N

SINGLE SUPPLY (+9V to +30V)

HIGH EFFICIENCY, >88%

DIGITAL VOLUME CONTROL, ANTI-

CLIPPING AND AUTOMATIC MUTE

THERMAL OVERLOAD AND SHORT

CIRCUIT PROTECTION

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.

BENEFITS

COMPLETE SURFACE MOUNT DESIGN

SMALL PACKAGE -NO HEAT SINK

POWER SUPPLY SAVINGS

ALL DIGITAL - NO DAC

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.
