UTC2030
LINEAR INTEGRATED CIRCUIT
18W Hi-Fi AMPLIFIER AND
35W DRIVER
DESCRIPTION
The UTC2030 is a monolithic IC in Pentawatt package
intended for use as low frequency class AB amplifier.
With Vsmax=32V it is particularly suited for more reliable
applications without regulated supply and for 35W driver
circuits using lowcost complementary pairs.
The UTC2030 provides high output current and has very
low harmonic and cross-over distortion.
Further the device incorporates a short circuit protection
system comprising an arrangement for automatically limiting
the dissipated power to as to keep the working point of the
output transistors within their safe operating area. A
conventional thermal shut-down system is also included.

method for the measurement of TIM consicts of feeding sine waves superimposed onto square wavers,into the
amplifier under test.The output spectrum is then examined using a spectrum analyser and compared to the
input.This method suffers from serious disadvantages:the accuracy is limited, the measurement is a tather delicate
operation and an expensive spectrum analyser is essential.A new approach (see Technical Note 143(Applied by
SGS to monolithic amplifiers measurement is fast cheap,it requires nothing more sophisticated than an
oscilloscope-and sensitive-and it can be used down to the values as low as 0.002% in high power amplifiers.
The "inverting-sawtooth" method of measurement is based on the response of an amplifier to a 20KHz sawtooth
waveform.The amplifier has no difficulty following the slow ramp but it cannot follow the fast edge.The output will
follow the upper line in Fig.23 cutting of the shade area and thus increasing the mean level.If this output signal is
filtered to remove the sawtooth,direct voltage remains which indicates the amount of tIM distortion, although it is
difficult to measure because it is indistingishable from the DC offset of the amplifier.This problem os neatly avoided
in the IS-TIM method by periodically inverting the sawtooth waveform at a low audio frequency as shown in
Fig.24.Inthe case of the sawtooth in Fig. 25 the means level was increased by the TIM distortion, for a sawtooth in
the other direction the opposite is ture.
