18W HI-FI AUDIO AMPLIFIER AND
35W DRIVER
DESCRIPTION
The UTC TDA2030A is a monolithic IC in Pentawatt
package 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.
