8 Parameter Measurement Information

All parameters are measured according to the conditions described in the Specifications section.

Many audio analyzers will not give the correct readings on a Class-D amplifier without additional filtering, even if they have an internal low-pass filter. A RC 30kHz low-pass filter (100-Ω, 47n-F) is implemented to reduce the remaining noise frequencies from the PWM carrier signal. This filter was used on each output for the data sheet graphs.
