The thermocouple and temperature sensor schematic of the LMP90100 Evaluation Board are
shown below. The temperature sensor is a LM94022 and is located under the thermocouple
connector (J4) to provide cold junction compensation. The thermocouple connector (J4) is made
for use with a type K thermocouple. The following subsections will explain how to configure the
LMP90100EB for the thermocouple and IC temperature sensor applications.
