AD7414

The AD7414/AD7415 is a complete temperature monitoring system in 6-lead and 5-lead SOT-23 packages. 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/AD7415 provides a 2-wire serial interface that is compatible with SMBus and I2C interfaces. The part comes in four versions, AD7414/AD7415-0, AD7414/AD7415-1, AD7414-2 and the AD7414-3. The AD7414/AD7415-0 and AD7414/AD7415-1 versions allow for 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 AD7415 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 it 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 Over-Temperature Indicator output (ALERT), which becomes active when a programmed limit is exceeded. A configuration register allows programming of the sense of the ALERT output (active high or active low). This output can be used as an interrupt or as an SMBus alert.
