AMP02FSZ-RL Application Field and Working Principle

AMP02FSZ-RL is a linear amplifier and instrumentation op-amp with a rail-to-rail output and is capable of driving rail-to-rail input levels even at high supply voltages. It is usually available with 1.8V, 3V and 5V supply voltage ratings and offers rail-to-rail output swing at ±12V. The op-amp features low noise and low bias current performance. It is characterized by low offset voltage, low quiescent current and wide supply voltage range.

Applications

The AMP02FSZ-RL is suitable for a wide range of applications such as signal conditioning, transducer amplifier, transimpedance amplifier and data acquisition systems. It can also be used in audio amplifiers, audio signal processing circuits, voltage to current converters and photodiode amplifiers. It is suitable for both consumer and industrial applications.

Working Principle

The working principle of the AMP02FSZ-RL amplifier is based on a standard op-amp architecture. It consists of two identical differential amplifiers working in tandem. The first differential amplifier compares the voltages of the input signal with its own reference voltage. This reference voltage is set using the op-amp’s offset voltage. The second differential amplifier compares the output voltage of the first amplifier with its own reference voltage. This reference voltage is also set using the op-amp’s offset voltage. The output of the second amplifier produces the output signal which is used for the desired application.
