3. Description
The MLX90640 is a fully calibrated 32x24 pixels IR
array in an industry standard 4-lead TO39 package
with digital interface
The MLX90640 contains 768 FIR pixels. An
ambient sensor is integrated to measure the
ambient temperature of the chip and supply
sensor to measure the VDD. The outputs of all
sensors IR, Ta and VDD are stored in internal RAM
and are accessible through I2C.
