1.0 GENERAL DESCRIPTION
The DDX-2160, DDX-2120 and DDX-2100 power
devices are monolithic, dual channel H-Bridges that
can provide audio power up to:
• 80 watts per channel @10%THD, 6Ω (DDX-2160)
• 75 watts per channel @10%THD, 8Ω (DDX-2160,
DDX-2120)
• 65 watts per channel @10%THD, 8Ω (DDX-2100)
at very high efficiency.
Each device contains a logic interface, integrated
bridge drivers, high efficiency MOSFET output
transistors and protection circuitry. Each device
may be used in DDX® Mode as a dual bridge or
reconfigured as a single bridge with double the
output current capability. Alternatively, in Binary
Mode, it may be configured as either a dual bridge
or (at lower power output) a quad half-bridge or a
combination of both types.
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 PWM
designs of more than three times the efficiency of
typical Class A/B amplifiers with music input
signals.
