Renesas Electronics ZSC31010 Resistive Sensor Signal Conditioner
Renesas Electronics ZSC31010 Resistive Sensor Signal Conditioner (SSC) is a CMOS integrated circuit that enables easy and precise calibration of resistive bridge sensors via EEPROM. When mated to a resistive bridge sensor, the ZSC31010 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.
The ZSC31010 SSC communicates via a ZACwire™ serial interface to the host computer and is easily mass-calibrated in a Windows environment. Once calibrated, the output SIG™ pin can provide a selectable 0V to 1V absolute analog output, a rail-to-rail ratiometric analog output, or digital serial output of bridge data with optional temperature data.
