3 / 32 page  TS4909 Typical application schematics 3/32 1 Typical application schematics Figure 1. Typical applications for the TS4909 Table 1. Application component information Component Functional description Rin1,2 Inverting input resistor that sets the closed loop gain in conjunction with Rfeed. This resistor also forms a high pass filter with Cin (fc = 1 / (2 x Pi x Rin x Cin)). Cin1,2 Input coupling capacitor that blocks the DC voltage at the amplifier’s input terminal. Rfeed1,2 Feedback resistor that sets the closed loop gain in conjunction with Rin. AV= closed loop gain = -Rfeed/Rin. Cb Half supply bypass capacitor. Cs Supply bypass capacitor that provides power supply filtering.
