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 pr...
