Current sense amplifiers are integrated circuits with operational amplifiers and sense resistors that are used in measuring the amplitude and direction of current in circuits

Amplifier and comparator chips are board-level components for amplifying voltage, current, or power

Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels.

Power operational amplifiers (POA) are used to increase the power of low-level signals in applications that drive low impedances or reactive loads.

Piezoelectric devices generate electrical signals in response to vibrations and produce mechanical energy in response to electrical signals.

DC servomotors are generally small and powerful for their size, and easy to control.

Load cells are transducers for force and load measurement, often with mounting packaging.
