Working Principle

The MAX4489ASA+ works by utilizing a high gain amplifier, known as a differential amplifier, which amplifies the signal difference between its two input terminals. The gain of the amplifier is determined by the ratio of the output resistance of one of the inputs to the output resistance of the other input. This allows for a much higher gain than is typical in single-ended amplifiers. The MAX4489ASA+ also works to reduce noise and distortion by using a low-bias current technique with quiescent current stabilization to drive the differential amplifier. The low-bias current keeps the amplifier on an optimal trajectory, while the current stabilization ensures that the amplifier is running within the optimal biasing range.
