The NJM2136M amplifier is capable of providing high common mode rejection, low power consumption and low input bias current. It is widely used in audio preamplifier circuits and current sensing applications that require high precision and low distortion.

NJM2136M Working Principle

The NJM2136M amplifier works by taking two signals that represent movements of a given physical object, amplifying the difference between them and producing an output voltage. This output voltage is then used to measure the movement or position of the object.

The NJM2136M amplifier has a differential input stage consisting of two amplifiers connected in series. One of the amplifiers acts as a rectifier and the other acts as an inverter. The output of the differential input stage is then fed into a voltage divider network of resistors, which reduces the output voltage to a lower level. The voltage is then fed into the output stage, a differential amplifier, which amplifies the input signal and produces an output voltage.

The voltage divider network and differential input stage provide high common mode rejection and low bias current, making the NJM2136M amplifier suitable for precision current sensing, temperature sensing and audio preamplifier applications.
