MC33079DR2 Datasheet/PDFMC33079DR2 application field and working principle
The MC33079DR2 is a quad general-purpose operational amplifier (op-amp). It is an instrumentation amplifier whose four amplifiers share identical characteristics and general-purpose operation. In other words, it amplifies four different signals at once, in a single package. It is designed for use in applications such as audio amplifiers, microphone preamplifiers, bridge circuits, and motor control circuits.
It has a wide operating temperature range from -40°C to +85°C, a low power consumption of 177mW per amplifier, and a wide supply voltage range of 4V to 18V. The MC33079DR2 is equipped with a high slew rate of 1V/µs and a low input bias current of 20µA. The input impedance is extremely high so that it can preserve a signal with high fidelity. The input resistance of 33079 is also greater than 100 times greater than that of most other general purpose op-amps.
It can be used for different types of application from medical equipment to consumer electronics. Its slew rate and input impedance enable it to perform as a buffer amplifier. It can also be used as a noninverting amplifier for digital signals, a subtracting amplifier for measuring AC/DC voltages, and a precision rectifier for measuring DC voltages.
The basic operation of the MC33079DR2 is that it amplifies an incoming signal and then delivers the amplified signal to an output circuit. The MC33079DR2 employs an arrangement of two differential amplifier circuits to accomplish this. Each of these differential amplifiers produces voltage signals according to the difference between its respective input signals. The outputs of the two circuits are then amplified by the Voltage Buffer stage and sent to the output circuit.
The MC33079DR2 has two types of input pins: the inverting and the non-inverting pins. When the inverting pin is connected to ground and the non-inverting pin is connected to the input signal, the amplifier increases the voltage from the input signal to the higher voltage level of the output circuitry.
The MC33079DR2 also has an open collector output pin, which enables it to pass a number of signals without overloading the amplifier. The output of the MC33079DR2 is unaffected by the load impedance, which makes it ideal for use in bridge circuits, unity gain circuits, and high input impedance applications.
The MC33079DR2 is a versatile op amp that is suitable for a variety of general-purpose applications. It is a quad amplifier, which means that it can amplify four different signals at once, in a single package. It has a wide operating temperature range, low power consumption, and offers a high slew rate and low input bias current. It can be used to amplify digital signals, subtract offset, and measure DC voltages faithfully and accurately. Its open collector output pin further adds to its versatility.
