SM6610 series
NIPPON PRECISION CIRCUITS INC.
CMOS Monolithic Temperature Sensor IC
OVERVIEW
SM6610 series is high-accuracy temperature sensor IC in the ultra small package.
By using CMOS circuit, it realizes low voltage and low current consumption.
The power down function contributes to decrease the current consumption of application set by activating
intermittent function easily.
