2 General Description
The MLX90616 is an Infra Red thermopile sensor for high
temperature non-contact thermometers. Both the IR
sensitive thermopile detector chip and the signal
conditioning ASSP are integrated in the same TO-39 can.
A low noise amplifier, 17-bit ADC and powerful DSP unit,
result in a high accuracy and resolution of the
thermometer. The ambient temperature sensor in the
MLX90616 is calibrated in the factory. The digital interface
of the sensor is SMBus compatible.
The MLX90616 is intended to be used in applications where the user places a lens in front of the sensor to
adjust the FOV to his application. The sensor-lens combination temperature measurement has to be
calibrated by the customer. Melexis provides the necessary software to do this in an engineering
controlled environment.
The MLX90616 consists of a chipset developed and manufactured by Melexis:
 The Infra Red thermopile detector MLX81101
 The signal conditioning ASSP MLX90302, specially designed to process the output of IR sensor.
The device is available in an industry standard TO-39 package.
