The AD7414/AD7415ART-1REEL7 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/AD7415ART-1REEL7 provide a 2-wire serial interface that is compatible with SMBus and I2C 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 I2C addresses while the two AD7415ART-1REEL7 versions allow up to six I2C 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.
