SOT-23 10位数字温度传感器AD7414/AD7415

　　The AD7414/AD7415 are complete temperature monitoring systems in 6-lead and 5-lead SOT-23 packages. They contain a band gap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C. The AD7414/AD7415 provide a 2-wire serial interface that is compatible with SMBus and I2 C interfaces. The parts come in four versions： the AD7414/AD7415-0， AD7414/AD7415-1， AD7414-2， and AD7414-3. The AD7414/AD7415-0 and AD7414/AD7415-1 versions provide a choice of three different SMBus addresses for each version. All four AD7414 versions give the possibility of eight different I2 C addresses while the two AD7415 versions allow up to six I2 C addresses to be used. The AD7414/AD7415’s 2.7 V supply voltage， low supply current， serial interface， and small package size make them ideal for a variety of applications， including personal computers， office equipment， cellular phones， and domestic appliances. In the AD7414， on-chip registers can be programmed with high and low temperature limits， and an open-drain overtemperature indicator output （ALERT） becomes active when a programmed
