80×64 Thermopile Infrared Array


80×64 Thermopile Infrared Array

The HTPA80x64d is a small size, high performance, low cost thermopile infrared array for thermal imaging inside a TO-8 housing. Due to the digital SPI interface, only six pins are needed for operation. It has a 16-bit ADC and built-in EEPROM stores all calibration data. The framerate can be set individually and depends on the sensor clock and ADC resolution. For high 16-bit resolution, framerates of up to 20 Hz are possible, while lower ADC resolutions allow framerates of up to 30 Hz and more. Different available optical lenses, integrated with the array in TO-8 housing, provide fields of view (FOV) from 12×9 degree up to 120×90 degree.
