DESCRIPTION

Sensors are energy conversion devices. Sensors or transducers convert the physical world of light, pressure, temperature, flow, level, acceleration, force, etc. to electrical signals but generally they can’t do so without help. Excitation and/or signal conditioning electronics are almost always needed to interface the sensor and provide adjustable calibration, amplification, linear ization, and level transformation functions.

Digitally controlled potentiometers add variability and programmability to the sensor circuit and provide an automated alternative to manually adjusted mechanical trimmers. The results are accuracy, speed, reliability, packaging flexibility, and labor and cost savings.
