Description
The TDA2040 is a monolithic integrated circuit in
the Pentawatt® package, intended for use as an
audio class-AB amplifier. Typically, it provides
25 W output power into 4 Ω with THD = 0.5% at
VS = 34 V. The TDA2040 provides high output
current and has very low harmonic and crossover
distortion. Furthermore, the device incorporates a
patented short-circuit protection system

comprising an arrangement for automatically
limiting the dissipated power so as to keep the
operating point of the output transistors within
their safe operating range. A thermal shutdown
system is also included.
