Operational Amplifiers

Operationsverstärker
Operationsverstärker
The temperature detector fire alarm system consists of a thermistor sensor that initiates a small current flow in case of a fire. This signal is too weak ...
Eigenschaften des OpAmp
Eigenschaften des OpAmp
Consider the equivalent circuit model of an operational amplifier. The output section consists of a voltage-controlled source in series with the output ...
Invertierende und nicht-invertierende Operationsverstärker
Invertierende und nicht-invertierende Operationsverstärker
The inverting amplifier connects the input voltage through a resistor to the inverting terminal, grounds the non-inverting terminal, and has a feedback ...
Summen- und Differenz-Operationsverstärker
Summen- und Differenz-Operationsverstärker
A summing amplifier, or an adder, uses an operational amplifier to combine multiple input signals into a single output. Conversely, a difference ...
Eigenschaften praktischer Operationsverstärker
Eigenschaften praktischer Operationsverstärker
A difference amplifier containing a common and a difference-mode signal ideally amplifies only the difference-mode signal. However, in practical circuits, ...
Integrator und Unterscheidungsmerkmal
Integrator und Unterscheidungsmerkmal
Consider a car with cruise control using an op amp circuit to maintain a constant speed. This circuit employs the function of an op amp as an integrator ...
Kaskadierte Operationsverstärker
Kaskadierte Operationsverstärker
Operational Amplifiers can be connected in a cascade - one after another in linear sequence without altering their input-output relationships due to their ...
Instrumentenverstärker
Instrumentenverstärker
In an electrocardiography machine, electrodes detect small electrical changes on the skin resulting from heart muscle depolarization during each ...
