Voltage and current swings are twice for a bridge
amplifierincomparisonwithsingleendedamplifier.
In order words, with the same R
L
the bridge con-
figuration can deliver an output power that is four
times the outputpower of a singleended amplifier,
while,with thesamemax outputcurrent thebridge
configuration can deliver an output power that is
twice the output powerof asingle ended amplifier.
Core must be taken when selecting V
S
and R
L
in
order to avoid an output peak current above the
absolute maximum rating.
From the expression for I
Omax
, assuming V
S
= 14.4V and V
CE sat
= 2V, the minimum load that
can be driven by TDA2005 in bridge configuration
is :
