FUNCTIONAL DESCRIPTION
The TDA7056 is a mono output amplifier, designed for
battery-fed portable radios and mains-fed equipment such
as television. For space reasons there is a trend to
decrease the number of external components. For
portable applications there is also a trend to decrease the
number of battery cells, but still a reasonable output power
is required.
The TDA7056 fulfills both of these requirements. It needs
no peripheral components, because it makes use of the
Bridge-Tied-Load (BTL) principle. Consequently it has, at
the same supply voltage, a higher output power compared
to a conventional Single Ended output stage. It delivers an
output power of 1 W into a loudspeaker load of 8
with 6
V supply or 3 W into 16
loudspeaker at 11 V without
need of an external heatsink. The gain is internally fixed at
40 dB. Special attention is given to switch-on/off click
suppression, and it has a good overall stability. The load
can be short circuited at all input conditions.
