• Manufacturer Part Number: MLX90247_04
• Description: Discrete Infrared Thermopile Detectors
• Manufacturer: ETC2 [List of Unclassifed Manufacturers]

NOTE: The thermistor resistance can be calculated using following expresion:
Note:
Due to the strong ESD protection BAA and BAL versions can only be used with CM (Common Mode) = 0V
for IR outputs. When measuring resistances with an ohm meter, please take care that the internal
protection diodes, as indicated in the functional diagram below, are always reverse biased (DSA and DSL
versions).
