DESCRIPTION

The TDA 2051 is a monolithic integrated circuit in

Pentawatt package, intended for use as an audio

class AB amplifier. Thanks to its high power capa-

bility the TDA2051 is able to provide up to 40W

±18V, f

= 1KHz and up to 33W into 8ohm load @ THD =

±22V, f = 1KHz.

Moreover, the TDA 2051 delivers typically 60W

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

cost/space due to both, low number of external

parts and reduced heatsink area due to optimized

heatsink efficiency.
