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
typ. into 4 ohm load @ THD = 10%, V
S
=
18V, f
= 1KHz and up to 33W into 8ohm load @ THD =
10%, V
S
=
22V, f = 1KHz.
Moreover, the TDA 2051 delivers typically 60W
music power into 4 ohm load over 1 sec at V
S
=
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.
