High-precision and Low-power Analog Output Temperature Sensor

NST20 is a series of precision CMOS integrated circuit linear analog output temperature sensor. Input voltages range is from 2.4V to 5.5V. The maximum temperature error in the whole temperature range is within ±2.5℃. 20μA typical operating mode current and 0.1μA typical turn-off current can greatly reduce the power loss of battery-powered equipment. Class-AB output drivers provide a powerful maximum output of 500µA, which can drive capacitive loads up to 1000pF, and can be directly connected to the ADC sample-hold input end. With excellent accuracy and a powerful linear output driver, the NST20 analog output temperature sensor is an extremely cost-effective alternative to passive thermistors.
