MAX1450 EVALUATION KIT AVAILABLE Low-Cost, 1%-Accurate Signal Conditioner for Piezoresistive Sensors General Description The MAX1450 sensor signal conditioner is optimized for piezoresistive sensor calibration and temperature compensation.
It includes an adjustable current source for sensor excitation and a 3-bit programmable-gain amplifier (PGA).
Achieving a total typical error factor within 1% of the sensor’s inherent repeatability errors, the MAX1450 compensates offset, full-span output (FSO), offset tempco, FSO tempco, and FSO nonlinearity of silicon piezoresistive sensors via external trimmable resistors, potentiometers, or digital-to-analog converters (DACs).
The MAX1450 is capable o...
