GENERAL DESCRIPTION

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.

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°C.

PRODUCT HIGHLIGHTS

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.

1. On-chip temperature sensor. The sensor allows an accurate

measurement of the ambient temperature to be made. It is

capable of 0.5°C temperature accuracy.

2. SMBus/I²C-compatible serial interface. The interface offers pin

selectable choice of three addresses per version of the

AD7414/AD7415, eight address options in total for the AD7414,

and six in total for the AD7415.

3. Supply voltage of 2.7 V to 5.5 V.

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.

4. Space-saving 5-lead and 6-lead SOT-23 packages.

5. 10-bit temperature reading to 0.25°C resolution.

6. Overtemperature indicator. This indicator can be software

disabled. It is used as an interrupt of SMBus alert.

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

7. One-shot and automatic temperature conversion rates.
