Application Information
BRIDGE CONFIGURATION EXPLANATION
As shown in
Figure 1 , the LM4865 has two operational am-
plifiers internally, allowing for a few different amplifier con-
figurations. The first amplifier’s gain is DC voltage controlled,
while the second amplifier is internally fixed in a unity-gain,
inverting configuration. The closed-loop gain of the first am-
plifier is set by an external DC voltage (refer to (
Figure 1),
while the second amplifier’s gain is fixed by the two internal
20 k
Ω resistors.
Figure 1 shows that the output of amplifier one serves as the
input to amplifier two which results in both amplifiers produc-
ing signals identical in magnitude, but out of phase 180˚.
By driving the load differentially through outputs V
O1 and
V
O2, an amplifier configuration commonly referred to as
“bridged mode” is established. Bridged mode operation is
different from the classical single-ended amplifier configura-
tion where one side of its load is connected to ground.
A bridge amplifier design has a few distinct advantages over
the single-ended configuration, as it provides differential
drive to the load, thus doubling output swing for a specified
supply voltage. Four times the output power is possible as
compared to a single-ended amplifier under the same condi-
tions. This increase in attainable output assumes that the
amplifier is not current limited or clipped. In order to choose
an amplifier’s closed-loop gain without causing excessive
clipping, please refer to the Audio Power Amplifier Design
section.
