Working Principle

The MUSES8820E is an operational amplifier consisting of two input stages and a single output stage. The input stages are configured as complementary differential pairs with matched output impedances and input offset voltages, while the output stage consists of a gain stage with an output amplifier. The differential input stages amplifies the input signal and produces a voltage that is amplified by the output amplifier to obtain the amplified output signal.

The input stage consists of two matched complementary pairs with high gain and low input offset voltage. The current flowing through the input pairs is supplied by the bias current source and is controlled by the output voltage of the output amplifier. This ensures that the input offset voltage of the input stages is kept low.

The output stage consists of an output amplifier that is connected to the output of the differential pairs and a feedback loop with a resistor and a capacitor. The output amplifier amplifies the input signal and the capacitor and resistor form a low-pass filter that removes any high-frequency noise from the output signal. The output of the output amplifier is connected to the bias current source and can be used to control the bias current, thus further increasing the accuracy of the output signal.

The MUSES8820E is a high-performance device that can be used in a wide range of applications. It has a wide operating range, high common-mode rejection ratios and low offsets, making it ideal for applications such as instrumentation, linear, and buffer amplifiers. As such, it is the ideal choice for high-performance, low-noise applications.
