General Description
The MLX90620 is a fully calibrated 16x4 pixels IR
array in an industry standard 4-lead TO-39
package. It contains 2 chips in one package: the
Mlx90670 (IR array with signal conditioning
electronics) and the 24AA02 (256x8 EEPROM)
chip.
The MlX90620 contains 64 IR pixels with
dedicated low noise chopper stabilized amplifier
and fast ADC integrated. A PTAT (Proportional To
Absolute Temperature) sensor is integrated to
measure the ambient temperature of the chip. The
outputs of both IR and PTAT sensors are stored in
internal RAM and are accessible through I²C.
