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:

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:
