INTRODUCTION
The AD7414/AD7415 evaluation board allows the AD7414/
AD7415 digital temperature sensors to be quickly and easily
evaluated using a PC.
Using the evaluation board and its accompanying software, the
AD7414 /AD7415 evaluation board can be interfaced to any PC
running Windows® XP, Windows 2000, or later via one of the
computer’s USB ports.
The software allows the configuration of the board and the
monitoring of the AD7414/AD7415’s temperature readings.

THE AD7414/AD7415
This section gives a brief description of the AD7414/AD7415
and the system overview. Additional information can be found
in the
AD7414/AD7415
data sheet.
The AD7414/AD7415 are complete temperature monitoring
systems in a 6-lead SOT-23 (AD7414) package and a 5-lead
SOT-23 (AD7415) package. 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.
The AD7414/AD7415 provide a 2-wire serial interface that is
2
compatible with SMBus and I
four versions: the AD7414-0/AD7415-0, AD7414-1/AD7415-1,
AD7414-2, and AD7414-3. The AD7414-0/AD7415-0 and
AD7414-1/AD7415-1 versions provide a choice of three different
SMBus addresses for each version. All four AD7414 versions
give the possibility of eight different I
two AD7415 versions allow up to six I
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 PCs, 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 a SMBus alert.
