GENERAL DESCRIPTION

This user guide describes the ADT7x20 evaluation board

hardware and software and includes detailed schematics and

PCB layout artwork. The ADT7x20 evaluation board is a

compact, easy-to-use platform for evaluating all features of the

ADT7320 and ADT7420 temperature sensors.

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 is 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 either 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).
