rod _Description
te ^{P The TDA2040 is a monolithic integrated circuit in}
le ^{the Pentawatt® package, intended for use as an}
o ^{audio class-AB amplifier. Typically, it provides}
s _{25 W output power into 4 Ω with THD = 0.5% at}
b _{VS = 34 V. The TDA2040 provides high output}
O _{current and has very low harmonic and crossover}
- _{distortion. Furthermore, the device incorporates a}
) _{patented short-circuit protection system}
Pentawatt V
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.
