SGS Thomson Microelectronics TDA2030A Datasheet
18W Hi-Fi AMPLIFIER AND 35W DRIVER
DESCRIPTION
The TDA2030Ais a monolithic IC in Pentawatt
package intended for use as low frequency class
AB amplifier.
With V
reliable applications without regulated supply and
for 35W driver circuitsusing low-cost complementary pairs.
The TDA2030A provides high output current and
hasvery low harmonic and cross-overdistortion.
Furtherthe deviceincorporatesa short circuitprotection system comprising an arrangement for
automaticallylimitingthe dissipatedpowersoas to
keep the working point of the output transistors
within their safe operating area. A conventional
thermalshut-downsystem is also included.
