| 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. FEATURES s s pre lim ina s s s s s High linearity: 0.5% typ. (Ta = -20 to 80C) Operating temperature range: -40 to 100C (VDD 2.7V) Maximum output current load: 250A Output reference: VSS Low current consumption: 5.5A typ.
