MAX1450 Overview
The MAX1450 sensor signal conditioner is optimized for piezoresistive sensor calibration and temperature pensation. 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 pensates offset, full-span output (FSO), offset tempco, FSO tempco, and FSO...
