DESCRIPTIONThe 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 complemen-
tary pairs.
The TDA2030A provides high output current and
has very low harmonic and cross-over distortion.
Further the device incorporates a short circuit pro-
tection system comprising an 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.
