14.4 General remarks
14.5 SA58637BS PCB demo
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.
The application demo board may be used for evaluation single-ended input, BTL
differential output configuration as shown in the schematic in
(Figure
