The LMR358F-GE2 is a linear amplifier used in many applications that require high performance noise immunity and power efficiency such as precision measurement and instrumentation, operational amplifiers (OP amps), and buffer amps. Its ability to work as either a single supply or dual supply device makes it particularly well suited to applications where high noise immunity and power efficiency are essential.

Working Principle of LMR358F-GE2

The working principle of the LMR358F-GE2 is based on the differential amplifier topology. This topology allows the device to amplify the input signal without any additional offset voltage, and provides a higher level of accuracy than other topologies. Additionally, the device is designed to reduce overall noise and power consumption.

The LMR358F-GE2 is made up of two input stages, commonly referred to as the differential amplifier and the positive feedback amplifier. The differential amplifier contains two input transistors (mainly used for signal input) and two output transistors (mainly used for current gain) that are connected in an "L-configuration" to form an inverting and a non-inverting amplifier. The positive feedback amplifier, on the other hand, contains three transistors (two in the amplifier and one in the output buffer) that are connected in a "U-configuration" to form a non-inverting amplifier.

The differential amplifier is responsible for amplifying the input signal, while the positive feedback amplifier helps to improve the noise immunity and reduce current consumption. The output of the differential amplifier is fed directly to the positive feedback amplifier. The resulting output is a larger-amplitude signal with reduced noise and improved power efficiency compared to a single-stage amplifier.
