MAX1458 Datasheet | Maxim Integrated

19-1373; Rev 0; 5/98 1%-Accurate, Digitally Trimmed Sensor Signal Conditioner General Description The MAX1458 highly integrated analog-sensor signal processor is optimized for piezoresistive sensor calibration and pensation without any external ponents. It includes a programmable current source for sensor excitation, a 3-bit programmable-gain amplifier (PGA), a 128-bit internal EEPROM, and four 12-bit DACs. Achieving a total error factor within 1% of the sensor’s repeatability errors, the MAX1458 pensates offset, offset temperature coefficient, full-span output (FSO), FSO temperature coefficient (FSOTC), and FSO nonlinearity of silicon piezoresistive sensors. The MAX1458...
