Description
The TDA2040 is a monolithic integrated circuit in
Pentawatt
class AB amplifier. Typically, it provides 22 W
output power into 4 Ω with THD = 0.5% at
Vs = 32 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
