Electronic products are getting more and more popular in our daily life, and the demand for integrated circuits and other electronic components is also increasing. One of the most important components in the application of circuits is operational amplifier (op amp). EK47 is one of the most popular and widely used op amps in many electronic products. Through this article, we will introduce its application field and working principle.

EK47, also known as Series Extended Common Mode Range (ECMR) operational amplifier, has a high input impedance, low output impedance, high gain, good linearity, and wide bandwidth. It can work over a wide temperature range and the input and output waveforms remain stable. These features make EK47 suitable for high-speed op amp applications and low-voltage main power applications. It is also ideal for low-noise applications in mobile and telecom systems, computer peripherals, RF and IF receivers, audio systems, instrumentation amplifiers, and low-power analog-to-digital converters.

The working principle of EK47 is based on a differential amplifier consisting of two main transistors and two bias resistors. The differential amplifier is connected to a single-ended input signal on one side and a single-ended output signal on the other side. When a signal is applied at the input, it is split into two equal signals in the differential amplifier. These two signals will then be amplified, and an output signal will be generated. This output signal is larger in magnitude and in a single-ended form than the input signal. This is the basic working principle of EK47.

In summary, EK47 is an important component in the application of circuits. It is a popular op amp due to its wide range of features, including a high input impedance, low output impedance, high gain, good linearity, wide bandwidth, and wide temperature range. It is ideal for high-speed applications and low-voltage main power applications. Additionally, the working principle of EK47 is based on a differential amplifier and single-ended input and output signals.
