The AD7415 is a complete temperature monitoring system in a 5-pin SOT-23 package. It contains a bandgap temperature sensor and 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C.
The AD7415 provides a two-wire serial interface, which is compatible with SMBus and I2C interfaces. The part comes in four versions, the AD7415-0, AD7415-1, AD7415-2 and AD7415-3. The AD7415-0 and AD7415-1 versions allow for the choice of three different SMBus addresses each. All four versions combined give a possibility of eight different I2C addresses for the AD7415.
The AD7415's 2.7 V supply voltage, low supply current, serial interface and small package size, make it ideal for a variety of applications, including personal computers, cellular phones, office equipment and domestic appliances.
