GENERAL DESCRIPTION
The AD7414 is a complete temperature monitoring sys-
tem in a 6-pin SOT-23 package. It contains a bandgap
temperature sensor and 10-bit ADC to monitor and digi-
tize the temperature reading to a resolution of 0.25
oC.
The AD7414 provides a two-wire serial interface which is
compatible with SMBus and I
2C interfaces. The part
comes in four versions, AD7414-0, AD7414-1, AD7414-2
and the AD7414-3. The AD7414-0 & AD7414-1 versions
allow for the choice of three different SMBus addresses
for each version. All four versions give the possibility of
eight different I
2C addresses for the AD7414.
The AD7414’s 2.7V 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 appli-
ances.
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
SMBus is a trademark and I
2C is a registered trademark of Philips Corporation
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.
PRODUCT HIGHLIGHTS
1. The AD7414 has an on chip temperature sensor that
allows an accurate measurement of the ambient tem-
perature to be made. The measurable temperature range
is -55
oC to +135oC with a ±3oC temperature accuracy
over the full temperature range.
2. SMBus/I
2C
Compatible Serial Interface with pin
selectable choice of three addresses per version of the
AD7414, eight address options in total.
3. Supply voltage of 2.7V to 5.5V.
4. Space saving 6-Pin SOT-23 package.
5. 10-bit temperature reading to 0.25
oC resolution.
6. Over Temperature Indicator which can be software
disabled. Used as an interrupt of SMBus alert.
