Input protection circuit
First Claim
1. An input protection circuit installed within a non-inverted amplifier comprised of an operational amplifier that has an input signal on a non-inverted input terminal, a first resistor electrically connected between an output terminal and an inverted terminal of the operational amplifier, and a second resistor with one terminal electrically connected to the inverted terminal of the operational amplifier and the other terminal electrically connected to a base voltage of the input signal, wherein the input signal is raised to a predetermined high voltage higher than the ground level, wherein the input protection circuit comprises:
- a first diode with one end electrically connected to the non-inverted input terminal of the non-inverted amplifier and the other end electrically connected to the base voltage; and
a second diode having a cathode electrically connected to a power voltage of the non-inverted amplifier and an anode connected to the base voltage.
