Description
Technical field
A kind of 555 integrated package multiplication of voltage function presentation instrument are the utility model is related to, belong to Technical Teaching instrument field.
Background technology
At present, in Technical Teaching, the not no multiplication of voltage function presentation instrument on 555 integrated packages, student can not be deep
Understand the multiplication of voltage function of 555 integrated packages, this demonstration instrument can demonstrate 555 integrated package multiplication of voltage functions.
Utility model content
The purpose of this utility model is to provide a kind of 555 integrated package multiplication of voltage function presentation instrument, can demonstrate 555 integrated package multiplication of voltages
Function.
What the purpose of this utility model was realized in：Circuit is by dc source E, switch S, adjustable resistance R1, resistance R2、
Resistance R3, integrated package I, capacitor C1, capacitor C2, capacitor C3, capacitor C4, diode D1, diode D2, voltmeter V1, electricity
Press Table V2, oscillograph Q composition.It is characterized in that：Integrated package I, capacitor C1, capacitor C2, resistance R2, resistance R3Form multi-harmonic-oscillations
Device, adjustable resistance R1For changing voltmeter V1Reading be+5 volts, integrated package I NE555 ,+5 volt supply voltages are changed into
Square-wave pulse, exported from integrated package I 3 pin, when integrated package I 3 pin output is " 0 " ,+5 volt supply voltages are through diode D1
So that capacitor C3It is fully charged, capacitor C3Upper voltage is 5 volts, and the negative right side in a left side is just；When integrated package I 3 pin output is "+5 volt ",
Capacitor C3Left end voltage is risen to "+5 volt " by " 0 ", due to capacitor C3Both end voltage can not be mutated, capacitor C3Right-hand member electricity
Pressure is by "+5 volts, rising to "+10 volt ", and through diode D2To capacitor C4Charging, capacitor C4Upper voltage left end is "+5 volt ",
Right-hand member is "+10 volt ", realizes multiplication of voltage output.Oscillograph Q is used for demonstrating integrated package I 3 pin waveforms, voltmeter V2Display with
Voltmeter V1Multiple proportion.
Because using above-mentioned technical proposal, advantage and good effect are possessed by the utility model：It is integrated that 555 can be demonstrated
Block multiplication of voltage function, simple in construction, directly perceived accurate, operation demonstration is convenient.
