Description
The ZSC31010 is a CMOS integrated circuit, which enables easy and precise calibration of resistive bridge sensors via EEPROM. When mated to a resistive bridge sensor, it will digitally calibrate offset and gain with the option to calibrate offset and gain coefficients and linearity over temperature. A second-order compensation can be enabled for temperature coefficients of gain or offset or bridge linearity. ZSC31010 communicates via IDT's ZACwire™ serial interface to the host computer and is easily mass calibrated in a Windows™ environment. Once calibrated, the output SIG™ pin can provide selectable 0 to 1 V absolute analog output; rail-to-rail ratiometric analog output; or digital serial output of bridge data with optional temperature data.
