Working Principle

The MAX952ESA+T linear amplifier operates on the principle of voltage gain. This is achieved by using the amplifier’s input and output stages to amplify the input signal so that it produces a greater output. The amplifier has two main stages - the input and the output stages. The input stage uses a differential amplifier which is configured to provide a precise gain of approximately times two. The output stage is a current-feedback amplifier, which is configured for a precise gain of 1 + R2/Rf, where R2 and Rf are the feedback resistor and the feedforward resistor respectively.The amplifier also contains a number of precise voltage references which enable it to regulate its output. The references provide a precise voltage reference to the amplifier’s input and output stage and also provide precision levels of gain and operation stability. The amplifier also has a high common-mode rejection ratio (CMRR) of 80dB which helps to reduce any interference between the input and output stages.The MAX952ESA+T linear amplifier is designed for low-power precision applications and is capable of producing a wide range of output voltages from +15V to -15V with a minimum supply voltage of 2V. It has a high gain-bandwidth product of 20MHz and a high common-mode rejection ratio of 80dB making it an ideal choice for low-noise signal processing applications. Its features and precise voltage references also make it suitable for a variety of industrial control applications, such as data acquisition, power supply regulation and automotive electronic systems.
