AD7414 SMBus/I2C Digital Temperature Sensor in 6-Pin SOT with SMBus Alert and Over Temperature Pin
The AD7414 is a complete temperature monitoring system in a 6-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 AD7414 provides a two-wire serial interface, which is compatible with SMBus and I2C interfaces. On-chip registers can be programmed with high and low temperature limits. An ALERT output (SMBus compatible) becomes active when the high temperature limit is exceeded.
The part comes in four versions, the AD7414-0, AD7414-1, AD7414-2 and the AD7414-3. The AD7414-0 and AD7414-1 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 AD7414.
The AD7414'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.
Also see the AD7415, which a sister part to the AD7414 in a 5-Lead SOT-23. This part does not have the SMBus Alert Functionality.
