Signal conditioner
Modem sensing systems typically include a sensor, a microprocessor, and an A/D converter coupled there between. Sensors typically provide a low-level signal which needs to be amplified before being of use. Major error sources in such a system include offset error and gain error. Transducers are used in a wide variety of engineering applications to convert various physical quantities to an electrical signal. Sensors are generally coupled in transducers through at least a rudimentary signal conditioning circuit to electronic instrumentation for use in an application. The conditioning circuit is typically an analog circuit, as opposed to a digital circuit. Signal conditioning circuits are generally built around amplifiers and accurate amplifiers for use in precision signal conditioners took the form of an operational amplifier or an instrumentation amplifier.
