The invention discloses a current signal anti-jitter circuit. An external milliampere signal is accessed to a circuit input end, the circuit input end is connected in series with a first resistor and then connected with an analog switch control signal input end, and an analog switch control signal output end is connected in series with an analog switch normally open switch and then connected with an in-phase input end of an operational amplifier; the analog switch control signal output end is connected in series with a second resistor and then grounded, the in-phase input end of the operational amplifier is grounded through a capacitor, the inverting input end of the operational amplifier is connected with the output end of the operational amplifier, and the output end of the operational amplifier is connected in series with a third resistor and then connected to a control system; and current jitter of the control system caused by interruption of current input signals can be prevented, and safety and stabilit
