Working principle

The working principle of a MAX4238ASA-T consists of three stages- the input stage, amplifier stage and output stage. The input stage consists of a differential pair of high input impedance transistors (M1 and M2). The transistors have a gain of three by connecting the sources of M1 and M2 in series. This differential pair receives the input signal, amplifies it and passes it to the output stage. The amplifier stage consists of an op-amp with a common mode voltage reference. The amplifier stage amplifies the input signal and then passes the output signal to the output stage. The output stage consists of two complementary transistors that drives the output current.
