Tattalin Op Amp

Amplifier linear kamar op amp tana da yawan applications. Tana da gain na open loop mai karfi, input impedance mai karfi da output impedance mai kucin. Tana da common mode rejection ratio mai karfi. Saboda haka, ana amfani da shi don yawan applications. A cikin wannan article, muna neman wasu applications mafi inganci na op amp. Wannan ba list ta duka ne, amma tana daya daga manyan applications na op amp.

Applications na Op Amp as Inverting Amplifiers

Op-Amp zai iya amfani a matsayin inverting amplifier.

• Circuits na inverting, da ake yi da Op-Amp, suna da tsari, distortion ya kama, suka bayarawa masu transitory response mai karfi.

• Idan Op-Amp an amfani a cikin closed loop, akwai tsari na linear wajen input da output.

• Inverting amplifier zai iya amfani don unity gain idan Rf = Ri (indaba, Rf shine feedback resistor da Ri shine input resistor)

Applications na Op Amp as Non Inverting Amplifiers

A lokacin da input signal ya fara zuwa non-inverting input (+), output ya fara zuwa input ta hanyar feedback circuit da Rf da Ri (indaba, Rf shine feedback resistor da Ri shine input resistance).

• Voltage gain bili gare phase inversion. A cikin equivalent transistor, ana bukatar minimum 2 transistor stages don haka.

• Input impedance mai karfi musamman da Inverting input.

• Easily adaptable voltage gain.

• Total remoteness na signal supply daga output.

Application na Op Amp as a Phase Shifter

Op-Amp an amfani a direct coupling procedure, saboda haka DC voltage level a terminal na emitter yana zama dari phase zuwa phase. Yadda DC level na yake zama yana iya sa operating point na upcoming stages. Saboda haka, don yinza yadda voltage swing yake zama, an amfani da phase shifter. Phase shifter yana yi aiki ta zama ta add DC voltage level zuwa output na fall stage don pass output zuwa ground level.

Op Amp as Scale Changer

Op-Amp yana yi aiki a scale changer through small signals with constant-gain a cikin inverting da non-inverting amplifiers.

Non-inverting terminal ya kasance a ground, inda R1 tana link input signal v1 zuwa inverting input. Feedback resistor Rf tana connect output zuwa inverting input. Closed loop gain na inverting amplifier yana yi aiki based on the ratio of the two external resistors R1 and Rf and Op-Amp acts as a negative scaler when it multiplies the input by a negative constant factor.
While in need for an output that is equal to input for getting multiplied by a positive constant the positive scaler circuit is used by applying negative feedback.

Applications na Op Amp as Adder or Summing Amplifier

Op-amp zai iya amfani don sum input voltage na sources biyu ko da yawa zuwa single output voltage. Daga cikin diagram na circuit, ana neman application na op-amp as adder or summing amplifier. Input voltages an fara zuwa inverting terminal na op-amp. Inverting terminal ya kasance a ground. Output voltage proportional to the sum of the input voltages.

Applications na Op Amp as a Differential Amplifier
