Evaluating the ADT7320/ADT7420 Temperature Sensors
FEATURES
GENERAL DESCRIPTION
Supports the ADT7320 and ADT7420 temperature sensors
Powered from USB port—no additional power supply
required
PC software for control of temperature sensors
Supported operating systems: Windows 2000 and higher
Additional external evaluation board for remote
temperature measurements (ADT7x20EBZ)
Additional external flex boards for faster thermal response
This user guide describes the EVAL-ADT7x20EBZ,
ADT7320FBZ, and ADT7420FBZ evaluation board hardware
and software and includes detailed schematics and PCB layout
artwork. The ADT7x20 (EVAL-ADT7x20EBZ) evaluation
board is a compact, easy-to-use platform for evaluating all
features of the ADT7320 and ADT7420 temperature sensors.
The ADT7x20FBZ flex boards are optional extras to the
evaluation kit, which can be used as an extension to the
ADT7x20 evaluation board or as standalone devices for
interfacing with a microcontroller or FPGA.
EVALUATION KIT CONTENTS
Fully fitted printed circuit board (PCB) with USB interface
Additional external PCB
Evaluation software CD
USB cable
Documentation
Wiring guide
The evaluation kit allows the user to evaluate the performance
of the ADT7320 and ADT7420 temperature sensors using a PC.
The kit consists of two boards; a main board connected to the
PC through the USB port and an external board. The external
board and flex board are attached to the main board using wires
that can withstand high temperatures, and can be used for
remote temperature measurements in oil baths or ovens where
the temperature exceeds the specifications of the USB cable.
OPTIONAL EQUIPMENT
ADT7320FBZ flex board
ADT7420FBZ flex board
The evaluation software allows the user to select the main
board or the external board, as well as the desired temperature
sensor device.
When using the ADT7x20 evaluation board, in addition to this
user guide, the user should also consult the ADT7320 and
ADT7420 data sheets (available at the Analog Devices, Inc.,
website, www.analog.com).
