• Manufacturer Part Number: mlx90323
• Description: 4 ? 20 Ma Loop Sensor Interface With Signal Conditioning And Eeprom
• Manufacturer: Melexis Company

Note: Because of space considerations, the measured temperature can’t be kept in the RAM at all times. If
the measured temperature is to be available, the temperature filter variable, N_Factor, must be set to 6.
