TDA2030A
LINEAR INTEGRATED CIRCUIT
18W HI-FI AUDIO AMPLIFIER
AND 35W DRIVER
„ DESCRIPTION
The UTC TDA2030A is a monolithic IC intended for use as
low frequency class AB amplifier.
With Vs=max=44V it is particularly suited for more reliable
applications without regulated supply and for 35W driver circuits
using low-cost complementary pairs.
The UTC TDA2030A provides high output current and has
very low harmonic and cross-over distortion.
Further the device incorporates a short circuit protection
system comprising and arrangement for automatically limiting
the dissipated power so as to keep the working point of the
output transistors within their safe operating area. A
conventional thermal shut-down system is also included.

LINEAR INTEGRATED CIRCUIT
The result is an AC signal at the output whole peak-to-peak value is the TIM voltage, which can be measured
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:
VOUT
TIM =
* 100
Vsawtooth
In Fig.8 The experimental results are shown for the 30W amplifier using the UTC TDA2030A as a driver and a
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.
The Diagram of Fig.9 can be used to find the Slew-Rate(SR) required for a given output power or voltage and a
TIM design target.
For example if an anti-TIM filter with a cutoff at 30kHz is used and the max. peak to peak output voltage is 20V then,
referring to the diagram, a Slew-Rate of 6V/µs is necessary for 0.1% TIM.
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
turn the amplifier into a radio receiver.
