Application Information  
BRIDGE CONFIGURATION EXPLANATION  
By driving the load differentially through outputs VO1 and  
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.  
V
As shown in Figure 1, the LM4870 has two operational am-  
plifiers internally, allowing for a few different amplifier con-  
figurations. The first amplifier’s gain is externally config-  
urable, while the second amplifier is internally fixed in a  
unity-gain, inverting configuration. The closed-loop gain of  
the first amplifier is set by selecting the ratio of Rf to R i while  
the second amplifier’s gain is fixed by the two internal 40 kΩ  
resistors. Figure 1 shows that the output of amplifier one  
serves as the input to amplifier two which results in both am-  
plifiers producing signals identical in magnitude, but out of  
phase 180˚. Consequently, the differential gain for the IC is:  
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. Consequently, four times the output power is  
possible as compared to a single-ended amplifier under the  
same conditions. This increase in attainable output power  
assumes that the amplifier is not current limited or clipped. In  
order to choose an amplifier’s closed-loop gain without caus-
