ProDescription
leteThe TDA 2050 is a monolithic integrated circuit in
oa Pentawatt package, intended for use as an
saudio class-AB audio amplifier.
bThanks to its high power capability the TDA2050
- Ois able to provide up to 35 W true RMS power into
)a 4 ohm load at THD = 0%, VS = ±18 V, f = 1 kHz
t(sand up to 32 W into an 8 ohm load at THD = 10%,
cVS = ±22 V, f = 1 kHz.
uMoreover, the TDA2050 delivers typically 50 W
dmusic power into a 4 ohm load over 1 sec at
roVS = 22.5 V, f = 1 kHz.

The high power and very low harmonic and
crossover distortion (THD = 0.05% typ, at
VS = ±22 V, PO = 0.1 to 15 W, RL= 8 ohm,
f = 100 Hz to 15 kHz) make the device most
suitable for both hi-fi and high-end TV sets.

5 Short-circuit protection
Short-circuit protection
The TDA2050 has an original circuit which limits the current of the output transistors. The
maximum output current is a function of the collector emitter voltage, hence the output
transistors work within their safe operating area. This function can therefore be considered
as 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.
