1. Semiconductor Sensor

Flame Detection Amplifier

This IC contains an operational amplifier and a comparator, achieving extremely low offset voltage with a single power supply. Since a single power supply can be used, this IC can be operated with the voltage from two batteries. Through the use of the operational amplifier and the comparator, this IC can amplify thermocouple electromotive force and detect ignition according to output from the amplifier, without using other parts. The low offset voltage improves accuracy of ignition detection.
