DDX-2100
All-Digital High Efficiency
Power Amplifier
GENERAL DESCRIPTION
The DDX-2100 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-2100 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.
