What is an Operational Amplifier?

An operational amplifier (op-amp) is a DC-coupled, high-gain differential amplifier. It is generally used to amplify small changes in voltage, and is often referred to as a “voltage amplifier.” By combining multiple op-amps, they can be used to create a wide range of functions, such as amplifiers, filters, integrators, etc. For a more complete understanding of the function of an op-amp, see the full tutorial: What is Op-Amp (Operational Amplifier)

Features of LMP7300MM/NOPB

It is impedance compensated and has adjustable offset voltage. It also features a higher frequency range than most general-purpose op-amps, making it suitable for high-frequency applications. It has an open-loop bandwidth of 100kHz, a unity-gain bandwidth of 30MHz, and a slew rate of 0.9V/μs. It also features a wide operation temperature range of -40°C to +85°C.

Working Principle of LMP7300MM/NOPB

The working principle of the LMP7300MM/NOPB is based on the general principles of an op-amp. It amplifies the difference between two analog inputs and produces an output voltage that is proportional to this input voltage difference. Its inputs are the differential pair and its output is called the single-ended output. The op-amp amplifies any difference between the two inputs, i.e. the positive- and the negative-input. When the input voltage is zero, the output voltage is also zero. The output voltage will be either positive or negative depending on the polarity of the input voltage.

When the input voltage increases and the output voltage changes polarity, the output voltage changes according to the gain of the op-amp. The gain of the LMP7300MM/NOPB is set in a unity-gain configuration where it has a gain of 1. The gain of the LMP7300MM/NOPB can be adjusted by using a feedback resistor, which can be connected directly to the output or to the input of the amplifier. This feedback action reduces the gain of the amplifier when the feedback is increased. In this way, the gain of the amplifier can be controlled and adjusted as desired.

Application Fields of LMP7300MM/NOPB

The LMP7300MM/NOPB is suitable for a wide range of applications.
