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.
