Transient intermodulation distortion (TIM)
Figure 28. TIM distortion versus output power
TDA2030A
te Product(s) The diagram of Figure 29 originated by STMicroelectronics can be used to find the slew
le rate (SR) required for a given output power or voltage and a TIM design target.
o For example if an anti-TIM filter with a cutoff at 30 kHz is used and the max. peak-to-peak
bs output voltage is 20 V then, referring to the diagram, a slew rate of 6 V/ms is necessary for
0.1% TIM. As shown slew rates of above 10 V/ms do not contribute to a further reduction in
- O TIM.
) Slew rates of 100 V/ms are not only useless but also a disadvantage in hi-fi audio amplifiers
t(s because they tend to turn the amplifier into a radio receiver.
