Title: Protecting circuit for output of operational amplifier
Inventor: SEKI TAKANORI
IPC: H03F1/42
Filed: 1981-02-09
Abstract: PURPOSE: To exert no influence on an output of an operational amplifier in a normal state, by providing plural diodes connected to the operational amplifier, and opening a circuit so that an excessive input provided from the outside is not provided to the operational amplifier.  
     CONSTITUTION: Diodes 2, 3 are connected in series so that the polarity is opposite to each other. An electric power source 4 supplies electric power to a connecting point 6a of the diodes 2, 3, and an electric power source 5 supplies electric power to connecting points 6b, 6c. In this state, the diodes 2, 3 are made to conduct by the electric power sources 4, 5. An input signal of a terminal 7 is amplified by an operational amplifier 1, and reaches a terminal 8 through the diodes 2, 3. The diodes 2, 3 are always in an on-state since they are connected in series between an output of the operational amplifier 1 and the terminal 8, and electric power is supplied from the electric power sources 4, 5. Accordingly, the output of the operational amplifier can be fetched from the terminal 8 in a state that there is scarcely loss. If an excessive input is provided to the terminal 8, one of the diodes 2, 3 cuts the excessive input by the polarity of this excessive input, and prevents the excessive input from reaching the operational amplifier 1.
