2.2 W BTL audio amplifier
14.5 General remarks
The frequency characteristics can be adapted by connecting a small capacitor across the
feedback resistor. To improve the immunity of HF radiation in radio circuit applications, a
small capacitor can be connected in parallel with the feedback resistor (56 k
); this
creates a low-pass filter.
14.6 SA58632BS PCB demo
The application demo board may be used for evaluation in either BTL or SE configuration
as shown in the schematics in
Figure 3
and
Figure 15
. The demo PCB is laid out for a
64.5 mm
