ADC analog-to-digital converter
address Character code that identifies a specific location (or series of locations)
in memory or on a host PC bus system.
amplifier The device that delivers power to operate the motor in response to
low-level control signals. In general, the amplifier is designed to operate
with a particular motor type. For example, you cannot use a stepper drive
to operate a DC brush motor.
