AmplifierCircuits

General Description:      The DDX-2060 power device is a monolithic dual   channel H-Bridge that can provide up to 50 watts   per channel of audio power at very high   efficiency. The DDX-2060 power device contains a logic interface, integrated bridge   drivers, high efficiency MOSFET output transistors and protection circuitry. The device   may be used as a dual bridge or reconfigured as   a single bridge with double the output current capability.   The benefits of the DDX amplification system are   an 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....
