APPLICATION NOTE 3649

MAX1464 Signal-Conditioner, Sensor Compensation Algorithm

By: Youssof Fathi

Abstract: This application note describes the MAX1464 signal conditioner's sensor compensation algorithm. This algorithm will compensate and calibrate a sensor signal applied to one of the MAX1464's ADC channels, thus providing offset and span correction over temperature. The discussion assumes that the supply voltage to the MAX1464 does not change during the compensation process.
