8.2 Audio Output Typical Performance Plots

8.2 Audio Output Typical Performance Plots

To avoid nonlinearities (distortion) introduced by the amplifier load inductor itself, all amplifier typical performance plots

use a resistor and not a simulated speaker load. No EMI filtering is populated on the amplifier outputs (OUT±).
