TDA2030
easily with an oscilloscope. If the peak-topeak value of the signal and the peak-to-peak of the inverting sawtooth are
measured, the TIM can be found very simply from:
low-cost complementary pair. A simple RC filter on the input of the amplifier to limit the maximum signal slope(SS) is
an effective way to reduce TIM.
TIM design target.
then, referring to the diagram, a Slew-Rate of 6V/µs is necessary for 0.1% TIM.
turn the amplifier into a radio receiver.
In Fig.8 The experimental results are shown for the 30W amplifier using the UTC TDA2030 as a driver and a
The Diagram of Fig.9 can be used to find the Slew-Rate(SR) required for a given output power or voltage and a
For example if an anti-TIM filter with a cutoff at 30kHz is used and the max. peak to peak output voltage is 20V
As shown Slew-Rates of above 10V/µs do not contribute to a further reduction in TIM.
Slew-Rates of 100V/µs are not only useless but also a disadvantage in hi-fi audio amplifiers because they tend to
The result is an AC signal at the output whole peak-to-peak value is the TIM voltage, which can be measured
