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.
