The operational amplifier 103 may be a circuit unit with a high amplification factor, and has a positive input terminal Vin (+) (also called a non-positive input terminal), a negative input terminal Vin (-) and an output terminal Vout. In general, common operational amplifiers include general-purpose operational amplifiers (e.g., μ a741, LM358, and LM 324), high-resistance operational amplifiers (e.g., LF355, CA3130, and CA 3140), low-temperature-drift operational amplifiers (e.g., OP07, and AD508 such as OP 27), high-speed operational amplifiers (e.g., LM318, μ a 715), low-power operational amplifiers (e.g., TL-022C, TL-060C), high-voltage high-power operational amplifiers (e.g., D41), and programmable logic control operational amplifiers (e.g., PGA 103A). The operational amplifier used in the present application may be any of the above operational amplifiers, and is not particularly limited herein.
The operational principle of the operational amplifier is as follows: when the voltage of the non-inverting input terminal Vin (+) is greater than the voltage of the inverting input terminal Vin (-), the output terminal Vout amplifies the output in the forward direction. When the voltage at the inverting input terminal Vin (-) is greater than the voltage at the non-inverting input terminal Vin (+), the output terminal Vout negatively amplifies the output.
