DESCRIPTION
The TDA 2051 is a monolithicintegrated circuit in
Pentawatt package, intended for use as an audio
classAB amplifier. Thanks to its high powercapability the TDA2051 is able to provide up to 40W
typ. into4 ohm load @ THD =10%, V
= 1KHz and up to 33W into 8ohm load @ THD =
10%, V
=±22V, f = 1KHz.

Moreover, the TDA 2051 delivers typically 60W
music power into 4 ohm load over 1 sec at V
22.5V,f =1KHz.
The very low harmonic and crossover distortion

performances make the device the most suitable
for Hi-Fi field application.
The low external component count and the good
power dissipation capability of the Pentawatt
Package allowes stereo sets reduced in
