GENERAL DESCRIPTION
FEATURES
o Medium Accuracy (±1%), Single-Chip Sensor Signal Conditioning o Rail-to-Rail® Output o Sensor Errors Trimmed Using Correction Coefficients Stored in Internal EEPROM— Eliminates Laser Trimming and Potentiometers o Compensates Offset, Offset TC, FSO, FSO TC, and FSO Linearity o Programmable Current Source (0.1mA to 2.0mA) for Sensor Excitation o Fast Signal-Path Settling Time (<1ms) o +5V Single Supply o Accepts Sensor Outputs from +10mV/V to +40mV/V o Fully Analog Signal Path MAX1478 The MAX1478 highly integrated, analog sensor signal processor is optimized for piezoresistive sensor calibration and compensation without any external components. 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 digital-to-analog converters (DACs). Achieving a total error factor within 1% of the sensor’s repeatability errors, the MAX1478 compensates offset, offset temperature coefficient, full-span output (FSO), FSO temperature coefficient (FSO TC), and FSO nonlinearity of silicon piezoresistive sensors.
