Differential amplifier chips are designed to amplify the difference between two input signals. They can amplify a small difference between two signal levels and ignore any common level shared between them.
IC drivers or gate drivers provide the current and voltage necessary to turn power switching elements such as MOSFETs or IGBTs either on or off, based on the logic output signals of a DSP, micro-controller or other logic device.
Microprocessor chips (MPU) are silicon devices that serve as the central processing unit (CPU) in computers. They contain thousands of electronic components and use a collection of machine instructions to perform mathematical operations and move data from one memory location to another.
