4.9 Application example: Differential-input BTL power stereo amplifier
The schematic in Figure 69 shows how to design the TS4984 to work in differential-input mode. For this
discussion, only the left-channel amplifier will be referred to.
Let:
R1R =R2L =R1, R2R =R2L =R2
CinR = CinL =Cin
The gain of the amplifier is:
In order to reach the optimal performance of the differential function, R1 and R2 should be matched at 1%
maximum.
