TDA2040
20-watt hi-fi audio power amplifier
Features
Wide supply voltage range, up to 40 V
Single or split supply operation
Short-circuit protection to ground
Thermal shutdown
Description
The TDA2040 is a monolithic integrated circuit in
Pentawatt package, intended for use as an audio
class AB amplifier. Typically, it provides 22 W
output power into 4
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
limiting the dissipated power so as to keep the
working point of the output transistors within their
safe operating area. A thermal shut-down system
is also included.
