14W Hi-Fi AUDIO AMPLIFIER
DESCRIPTION
The TDA2030 is a monolithic integrated circuit in
www.DataSheet4UPf.creeomnqtuaewnactyt®clapsasckAaBgea,minptleifniedr.eTdypfoicr aullsyeit
as a low
provides
14W output power (d = 0.5%) at 14V/4Ω; at ± 14V
or 28V, the guaranteed output power is 12W on a
4Ω load and 8W on a 8Ω (DIN45500).
The TDA2030 provides high output current and has
very low harmonic and cross-over distortion.
Further the device incorporates an original (and
patented) short circuit protection system compris-
ing 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 conventional thermal shut-down system is
also included.

4페이지 PRACTICAL CONSIDERATIONS
TDA2030
Printed circuit board
The layout shown in Fig. 16 should be adopted by
the designers. If different layouts are used, the
ground points of input 1 and input 2 must be well
decoupled from the ground return of the output in
which a high current flows.
Assembly suggestion
No electrical isolation is needed between the
www.DataSheet4U.com
package and the heatsink with single supply voltage
configuration.
Application suggestions
The recommended values of the components are
those shown on application circuit of fig. 13.
Different values can be used. The following table
can help the designer.
