UTC8207 - Low Frequency Power Amplifier
YOUWANG ELECTRONICS CO.LTD 2 UTC8207 1.
Adjustment of Voltage Gain LINEAR INTEGRATED CIRCUIT The voltage gain GV is obtained as follows by R1, R2 and Rf in fig.1.
Rf + R1+ R2 GV = 20log Rf + R1 When Rf=0, GV=56.5dB (Typ.) When Rf=120Ω, GV=45dB (Typ.) By increasing Rf, reduction of GV is possibl
