Application Information
TS4972
25/30
Application n°4 : Differential inputs BTL power
amplifier
In this configuration, we need to place these
components : R1, R4, R5, R6, R7, C4, C5, C12.
We have also : R4 = R5, R1 = R6, C4 = C5.
The differential gain of the amplifier is:
Note : Due to the VICM range (see Operating
Condition), GVDIFF must have a minimum value
shown in figure 84.
For Vcc=5V, a 20Hz to 20kHz bandwidth and
20dB gain BTL power amplifier you could follow
the bill of material below.
