Figure 8. Half-Bridge Binary Mode Output Power vs Supply <1% THD
(NOTE: Curves taken at f = 1 kHz and using a 330uF blocking capacitor.)
Figure 8 depicts the output power as a function of power supply voltages for loads of 4, 6, and 8 Ohms
when the DDX-2102 is operated in a half-bridge Binary Mode. Solid curves depict typical performance
and dotted curves depict the minimum current limit for the DDX-2102. Once again, the output power
curves assume proper thermal management of the power device’s internal dissipation.
NOTE: Output power at 10% THD is approximately 30% higher.
Specifications are subject to change without notice.
