ADI AD7414ARTZ-1REEL7

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℃. The AD7414/AD7415 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 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 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 limit is exceeded. A configuration register allows programming of the state of the ALERT output (active high or active low). This output can be used as an interrupt or as an SMBus alert.
