Flame Detection Amplifier
Monolithic IC MM1217
Flame Detection Amplifier MM1217
www.DataSheet4U.com
Outline
This IC is comprised of an operation amplifier, a comparator, and a reference power source. It is worthy of
note that the input offset voltage and the input offset voltage temperature drift of this operation amplifier are
one digit less than those of conventional products regardless of the single power supply. Formerly, offset
voltage adjustment was required for flame detection using a thermocouple on gas appliances, but with this IC
adjustment is not required.
Due to the single power supply, low current consumption, and low offset voltage, two batteries can be used
for operation, making it appropriate for equipment that amplifies the very small signal of portable equipment.
