2 à 2.2 W BTL audio ampliï¬er
14.4 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 kâ¦); this
creates a low-pass ï¬lter.
14.5 SA58637BS PCB demo
The application demo board may be used for evaluation single-ended input, BTL
differential output conï¬guration as shown in the schematic in Figure 3. The demo PCB
(Figure 16) is laid out for a 64.5 mm2 (10 in2) heat spreader (total of top and bottom heat
spreader area).
