SM3322ARA Optical Sensor IC OVERVIEW The SM3322ARA is a fluorescence detector IC with a built-in single picture element (pixel) photodiode of 1mm2 and programmable signal conditioning circuit. The IC has an optical filter on chip with target condition 640nm ± 60nm, and it integrates all the elements required for optical sensor into an ultra-miniature package. The signal condition circuit has a programmable gain amplifier with dark current compensation circuit, so that it can operate in wider temperature range. With 3 addressing bits, up to 8 SM3322ARA can be paralleled.
