Functional Diagram
Description
The MLX90247C is a thermopile sensor IC which
detects very small amounts of heat radiation. The
sensor consists of a membrane with a thermopile on
top of it.
The hot junctions of the thermopile are positioned
near the center of the membrane, the cold junctions
above the bulk silicon edge.
Due to the low thermal conductivity of the
membrane,

temperature to increase more at the center of the
membrane than at the edge above the bulk. This
temperature difference is converted to an electric
potential by the thermo-electric effect in the
thermopile junctions. No supply voltage is needed.

The sensor and thermistor can be used independent
of each other if desired, as the thermopile potential
is floating.
