GENERAL DESCRIPTION

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.

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.

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).
