Exam 35: Operational Amplifiers

Because the comparator's output voltage switches when V_in crosses zero, the circuit is sometimes called a

The 741 op amp, an industry standard is contained in an eight-pin IC and is made by several manufacturers.

An op amp is a high-gain, direct coupled, differential amplifier.

What is the sampling of a portion of the output signal from an amplifier and feeding it back either to aid or oppose the input signal called?

If an op amp's closed-loop voltage gain is decreased

An op amp specification indicating the maximum rate at which the output voltage can change is referred to as the

When each input voltage of a summing amplifier is amplified by a different factor, the circuit is called a

Designed into the 741 op amp is a compensating capacitor used to prevent undesirable oscillations within the op amp.

An op amp referred to as the ______________ has become an industry standard.

What can be used with diodes to rectify signals with peak values in the millivolt region?

The open-loop voltage gain of an op amp is its voltage gain when there is negative feedback.

With an inverting op amp, the input and output signals are

The ______________ capacitor of the 741 op amp is used to prevent undesirable oscillations within the op amp.

When the voltage at the op amp's inverting input is at the same potential as ground, but it can sink no current, this point is considered

What determines the voltage gain of a noninverting op amp?

Which of the following is not an advantage of negative feedback?

The first stage of every op amp is an emitter follower.

The signal applied to each differential amplifier input is assumed to have exactly the same phase and amplitude, hence the name ______________-mode input.

Two identical signals applied to the inputs of an op amp, each with exactly the same phase relationship and voltage values is called a(n)

A filter that uses components or devices such as transistors and op amps, which can amplify, is called a(n)
