DDX-1080/DDX-1060/DDX-1050

1.0 GENERAL DESCRIPTION

The DDX-1080, DDX-1060 and DDX-1050 power
devices are monolithic, single channel H-Bridges
that can provide audio power up to:
•
90 watts one channel @10%THD, 8Ω (DDX-1080)
•
80 watts one channel @10%THD, 8Ω (DDX-1060)
•
65 watts one channel @10%THD, 8Ω (DDX-1050)
at very high efficiency.
Each device contains a logic interface, integrated
bridge drivers, high efficiency MOSFET output
transistors and protection circuitry.
may be used in DDX® Mode as a single bridge or,
alternatively in Binary Mode, it may be configured
as either a single bridge or (at lower power output)
a dual half-bridge.
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).
efficiency advantage over conventional PWM
designs of more than three times the efficiency of
typical Class A/B amplifiers with music input
signals.
