Sensor signal conditioners are commonly used in sensing systems to accept information from the sense element and turn it into meaningful data for further analysis. Sensor signal conditioners play a key role in removing sensing non-idealities and process the data to attain precise measurements.The Texas Instruments PGA devices are sensor signal conditioners that can directly connect to the sensing element. These highly integrated system-on-chip ICs measure and apply gain to the signal by using an internal low-noise instrumentation amplifier (IA) and pass it to an analog-to-digital converter (ADC). The ADC data is then processed by an internal digital signal processing engine that compensates for the sensor non-idealities in order to output data that can be extracted by a variety of output interfaces that can be analog or digital.
