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
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, integrated ADC. 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.
