TDA2040

25-watt hi-fi audio power amplifier

Datasheet

Features

Description

The TDA2040 is a monolithic integrated circuit in

audio class-AB amplifier. Typically, it provides

25 W output power into 4

Ω with THD = 0.5% at

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.
