Application Information
The TS4984 integrates two monolithic power amplifiers with a BTL (Bridge Tied Load) output
type (explained in more detail in
Section 4.1). For this discussion, only the left-channel amplifier
will be referred to.
Referring to the schematic in
Figure 62, we assign the following variables and values:
Vin = Vin1-
Vout1 =VOUT1+
Vout2 =VOUT1-
Rin = Rin1
Rfeed =Rfeed1
Cfeed =Cfeed1
4.1
BTL configuration principle
BTL (Bridge Tied Load) means that each end of the load is connected to two single-ended
output amplifiers. Thus, we have:
Single-ended output 1 = Vout1 =Vout (V),
Single-ended output 2 = Vout2 =-Vout (V), Vout1 -Vout2 =2Vout (V)
