Abstract
Apparatus and an accompanying method for calibrating a sensor signal conditioner coupled to a sensor. The signal conditioner sensor enables relatively easy and precise calibration of bridge sensors without the use of a microprocessor. When mated to a resistive bridge sensor, the sensor signal conditioner can digitally calibrate offset and gain, with an option to calibrate offset and gain coefficients and linearity over temperature. A second order compensation can be enabled for temperature coefficients of gain, offset or bridge linearity.
