... RHF484 3 Achieving good stability at low gain At low frequencies, the RHF484 can be used in a low gain configuration as shown in Figure 24. At lower frequencies, the stability is not affected by the value of the gain, which can be set close to 1 V/V (0 dB), and is reduced to its simplest expression G1=1+Rfb/Rg. ...
