MAX1478CAE-T

Sensor And Detector Interfaces Overview

The MAX1478CAE-T is a highly integrated analog sensor signal processor designed for piezoresistive sensor calibration and compensation. It integrates a programmable current source, a 3-bit programmable-gain amplifier (PGA), 128-bit internal EEPROM, and four 12-bit digital-to-analog converters (DACs). The device achieves a total error factor within 1% of the sensor’s repeatability errors by compensating offset, offset temperature coefficient, full-span output, FSO temperature coefficient, and FSO nonlinearity. It operates with a single supply voltage ranging from 2.7V to 5.5V and functions across an industrial temperature range of -40°C to +85°C.
