Question

哪位大虾能给个常用功放IC的资料和参数，要尽量全面的，比如TDA2030等等。

Answer 1

The TDA2030 is a monolithic integrated circuit in
Pentawatt[ package, intended for use as a low
frequency class AB amplifier. Typically it provides
14W output power (d = 0.5%) at 14V/4W; at ± 14V
or 28V, the guaranteed output power is 12W on a
4W load and 8W on a 8W (DIN45500).
TheTDA2030 provideshigh outputcurrentand has
very low harmonic and cross-over distortion.
Further the device incorporates an original (and
patented) short circuit protection system comprising
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.
SHORT CIRCUIT PROTECTION
TheTDA2030hasan original circuit whichlimits the
current of the output transistors. Fig. 18 shows that
the maximum output current is a function of the
collector emitter voltage; hence the output transistors
work within their safe operating area (Fig. 2).
This function can thereforebe consideredas being
peak power limiting rather than simple current limiting.
It reduces the possibility that the device gets damaged
during an accidental short circuit from AC
output to ground.
